喷嘴挡板伺服阀工作原理
前置放大级工作原理
压力油经滤油器和节 流孔流到滑阀左、右两端 油腔和两喷嘴腔，由喷嘴 喷出，经阀芯中部流回油箱 力矩马达无输出信号时， 挡板不动，滑阀两端压力相 等。当矩马达有信号输出时，挡板偏转，两喷嘴与挡板之间 的间隙不等，致使滑阀两端压力不等，推动阀芯移动。
功率放大级工作原理
当前置放大级有压差信号 使滑阀阀芯移动时，主油路 被接通。滑阀位移后的开度 正比于力矩马达的输入电流， 则阀的输出流量和输入电流 成正比；当输入电流反向时， 输出流量也反向。滑阀移动 同时，挡板下端的小球亦随 同移动，使挡板弹簧片产生 弹性反力，阻止滑阀继续移动；挡板变形又使它在两喷嘴间的 位移量减小，实现了反馈。当滑阀上的液压作用力和挡板弹性 反力平衡时，滑阀便保持在这一开度上不再移动。

INTRODUCTIONThis manual provides instructions and procedures necessaryto install, operate and troubleshoot the Moog D661 Series Servo and Propor-tional Control Valves.2. OPERATIONGeneralThe Servovalves D661-G, S and H Series and the Proportional Flow Control Valves D661-P Series are throttle valves for 2-, 3- and 4-wayapplications. With proportional flow control valves, 5-way applications are also possible. These valves are suitable for electrohydraulic position, velocitiy,pressure or force control systems with high dynamic response requirements.D661-G, S and HThe spool of the main stage is driven by a nozzle flapper or ServoJet ®pilot stage, optional with or without additional mechanical feedback (nozzle flapper only).With versions D661-S and H in case of an electrical supply failurethe spool is moved into a preferred position by action of an additional mechanical feedback.E LE CTROHYDRAULIC VALVE CUT -AWAYFigure 1 Moog Series D661-G Series, without additional mechanical feedbackX T A P BT 2YConnectorSpoolBushingScrew Plug for Null AdjustSeries Models Series GServovalve with nozzle-flapper or ServoJet ® pilot stage, spool in bushing, without additional mechanical feedbackSeries S Servovalve configured like version G, but with additional mechanical feedbackSeries H Servovalve configured like version S, but with improved performance (high response)Series P ...A/B Proportional valve with ServoJet ® pilot stage, spool in body ,without additional mechanical feedbackSeries P ...F/GProportional valve configured like version P ...A/B, but with nozzle flapper pilot stage and additional mechanical feedbackJet pipe Annular areaNozzleReceiver2Operating Principle of the T wo-Stage ValveAn electric input signal (flow rate command) is applied to the integrated control amplifier which drives a current through the coils of the pilot stage torque motor. Thus the deflected nozzle-flapper system produces a pressure difference across the drive areas of the spool and effects its movement. The position transducer which is excited via an oscillator measures the position of the spool (actual value, position voltage).This signal is then rectified by a demodulator and is fed back to the control amplifier where it is compared with the command signal. The control amplifier drives the torque motor until command voltage and feedback voltage are equal.Thus, the position of the spool is proportional to the electric command signal.Proportional Flow Control Valve D661-...PThe nozzle flapper design of the pilot stage has been converted into an improved version with jet pipe amplifier (ServoJet ®).The ServoJet ® pilot stage consists mainly of torque motor, jet pipe and receiver.A current through the coil displaces the jet pipe from neutral. This displacement combined with the special shape of the nozzle directs a focussed fluid jet more into one receiver bore than into the other.The jet now produces a pressure difference in the control ports. This pressure difference results in a pilot flow, which in turn causes a spool displacement. The pilot stage drain is through the annular area around the nozzle to tank.Operating Principle of the T wo-Stage ValveAn electric input signal (flow rate command) is applied to the integrated control amplifier which drives a current through the coil of the pilot stage torque motor. The thus deflected jet pipe produces a pressure difference across the drive areas of the spool and effects its movement.The position transducer which is excited via an oscillator measures the position of the spool (actual value, position voltage). This signal is then demodulated and fed back to the controller where it is compared with the command signal. The controller drives the torque motor until the error between command signal and feedback signal is zero. Thus the position of the spool is proportional to the electric command signal.Failsafe Version D661-...PFor applications with proportional control valves where certain safety regulations are applicable, a defined metering spool position is needed in order to avoid potential damage. Therefore, failsafe versions are offered as an option for the MOOG proportional valves.After external triggering, this failsafe function causes a defined metering spool position.Mechanical Failsafe version (biased pilot stage with mechanical feedback)The safe position of the spool will be obtained after cut off of pilot pressure supply (external pilot connection) or operating pressure supply D661-P ...A/BWD661-P ...A/BU Proportional Valve D661-P ...A/BWand D661-P ...A/BU Series with electrically operated failsafe functionProportional Valve D661-P ...AP Serieswith electrically operated failsafe function2- stage Proportional Valve D661-...P ...A/B SeriesServovalve D661 - ...S and H Series with additional mechanical feedback3Electric characteristics of the 2/2-way solenoid valveFunctionelectro magnetic Nominal voltage 24 VDC Nominal power12 WDIN 43650-1Form A: 2+PE-PG9With failsafe versions R and L, a defined spool position is reached when the electric supply to the valve electronics is switched offwhile the pilot pressure is still applied. With version M, the resulting spool position is undefined.Electrically operated failsafe versionThe safe position of the spool will be obtained after switching off the integrated 2/2-way solenoid seat valve.With failsafe versions W , U and G, after cut-off of the solenoid, the spool moves to midposition. When the electric supply to the valveelectronics is switched off while the pilot pressure is still effective and the solenoid is still switched on, the spool will move to a defined end position with versions U and G.With failsafe version P , the integrated seat valve will shut off the external pilot pressure after switching off the solenoid.Cutting off the 24 VDC supply to the solenoid operated 2/2-way seat valveo protect relay contacts or semiconductors against damage, a Zener diode is required1)With version P at 210 bar pilot or operating pressure,with versions G ,S and H at 140 bar pilot or operating pressure,fluid viscosity of 32 mm˝/s and fluid temperature of 40°C.2)For long life wear protection of metering landsFor additional technical information such as dimensions, ordering information, etc., see the D660 series catalog.T echnical DataInternal/External Pilot Connection a.Conversion for operation with internal or external pilot connection.The pilot connection mode as shipped is indicated by the respective code letter of the type designation on the nameplate.With the 5-way version, where the T and T 2 ports are interchangedwith the P port, pilot supply port X and return portY must be connected externally.43.

SETTING UPThis information is valid for new installations to be put into operation as well as for repair cases.Filling the Hydraulic SystemNew oil is never clean. Therefore, the system should generally be filled by using a filling filter .This fine mesh filter should at least complywith the following requirement: ß10 ≈ 75 (10 µm absolute).Flushing the Hydraulic SystemBefore the hydraulic system is put into operation for the first time (also after modifications), it has to be flushed carefullyaccording to the instructions of the manufacturer of the plant / machine.a.Before flushing, suitable flushing elements have to be inserted in the pressure filters instead of the high pressure elements.b.Before flushing, the operational temperature of the hydraulic system should be achieved. Observe temperature!c.A flushing plate or, if the system allows, a directional valve should be mounted in place of the Moog porportional valve. The P- and T-connections are flushed through the flushing plate. The user A- and B-Attention: The directional valve can lead to unpermissablemovements in the load (i.e. with parallel drives), which may result in damage of the plant / machine. Instructions of the manufacturer have to be strictly observed.Minimum flushing time t can be calculated as follows:d.The flushing process can be considered completed when a system cleanliness of 15/12 according to ISO 4406 or 6 according to NAS1638 or better is achieved. A long life of the metering lands of the proportional valve can be expected for this cleanliness class.V = content of reservoir [gallons]Q = flow rate of the pump [gpm]t = V • 5Qe.Replace flushing elements in the pressure filters by suitable high pressure elements after flushing. Install Moog proportional valve instead of flushing plate or directional valve.Setting Up a.Set up machine/plant according to the operation instructions of the manufacturer after the valves have been installed. Vent hydraulic system!b.The safety instructions of the machine/plant manufacturer must be observed. Especially the safety requirements for machines like injection molding machines (EN 201), blow molding machines (EN 422) and die casting machines (EN 869), to name a few, are important.c.Observe oil temperature.d.Check hydraulic system for external leakage!6. MAINTENANCEBesides regular visual inspection for external leakage and filter replacement, maintenance work at the D661 Series valves is not required.Explosion proof valves D661K... must not be opened by the customer! Unauthorized opening will invalidate the explosion proof approval! Return failed valve to the factory.Moog valves can only be repaired at Moog Service Centers (for addresses see back page of this operation instructions).Filter ReplacementThe built-in filter disk protects orifices and nozzles against coarse contaminants. W ith severe contamination, the valve response will be reduced.Replace filter!Cleaning the filter is useless and may be dangerous!Before starting to work on the valve, clean the external surface around the filter cover!Attention: The filter disk (21) flows from inside to the outside.After removal of the cover (20) any contamination particles are on the insideof the disk (21) and therefore, cannot be seen from outside.a.Remove four internal hex bolts (38) using A llen wrench (3 mm). Removecover (20). Remove the filter disk (21) now accessible by using a scriber or a fine screwdriver as extraction tool.b.(53) for damage.Replace if necessary.c.Insert o-ring (53) first.

ELECTRICAL NULL ADJUSTMENTThe hydraulic null of the valve is preset at the factory with a tolerance of ± 2% of rated signal. If necessary, this null can be readjusted by the user of the valve.a.null! Contact machine/plant manufacturer.b.Procedure: Remove the command signal to the valve only by disconnecting command signal lead at the cabinet.Remove cover screw on electronics housing to access the null adjust potentiometer. Use a small screwdriver (blade width 2.5 mm) to turn the potentiometer screw either clockwise or counterclockwise. Usually it will not be necessary to turn the screw more than 2 turns in either direction (± 1 turn is equivalent to ± 15% null shift).c.While adjusting, watch the actuator (motor) motion to find the null position. With overlapped valves, turn the null adjust screw carefully in both directions to just start motion and then back into deadzone midposition between those two screw positions.d.After proper null adjustment, reconnect the command signal lead and install protective cover screw again.。

Only one load port (A) is used.The device operates like the 3-way PQ-Valve but with doubled flow rate into the load. A directional change of the load motion requires an external force.Without shuttle valve.The device operates from P ç A like a 3-way PQ-Valve. In the opposite direction P ç B it allows only flow modulation. By this means the direction of load motion can be reversed (open loop velocity control for load retract).Venting of pressure transducer Before first operation of the valve the internal lines of the pressure transducer must be carefully vented.When selecting the installation position of the valve care must be taken that the bleeding screw can become effective.If the load is located higher than the PQ-Valve the load also must be vented at its highest point.Caution: Vent only at reduced pressure! Danger of injury!With shuttle valve.The device operates as an electrically adjustable 4-way throttle valve, i. e. the load can be operated with pressure control in both directions of motion.Only one of the load ports is pressure controlled. The shuttle valve transmits the driving (higher) load pressure to the single pressure transducer. An electronic logic circuit provides for the coordination of motion direction and pressure control depending on the polarity of the flow rate command signal. The other port is more or less open to tank line which is provided by the special spool land location.The spring centered fail-safe version requires external pilot supply port X to be used.The device has parallel flow pathes and operates as elec-trically adjustable pressure relief valve from A ç T and B çT 2, res-pectively. At zero command signal the valve is fully open,i. e. the pressure in the load ports is zero apart from minor pres-sure build up due to line losses. A minimum pilot pressure (p X > 15 bar) has to be secured.This can be achieved by a check valve with 15 bar cracking pressure (as shown) or by a separate pilot supply pump.D691 SeriesTypical characteristic curvesFlow and pressure responseFlow step responseFrequency response (flow)Pressure step responseExamples for pressure step response showthe effect of valve flow setting and entrap-ped fluid volume on pressure controldynamics.

If required please contactMOOG for assistance.43Flow rate and pressure dropThe actual flow is dependent upon electrical command signal and valve pressure drop. The flow for a given valve pressure drop can be calculated using the square root function for sharp edged orifices as follows:Flow rate mode An electrical command signal (flow rate set point) is applied to the integrated position controller which drives the valve coil. The position transducer (LVDT) which is excited via an oscillator measures the position of the spool (actual value, position voltage).This signal is then demodulated and fed back to the controller where it is compared with the command signal. The controller drives the pilot valve until the error between command signal and feedback signal is zero. Thus the position of the spool is pro-portional to the electrical com-mand signal.Q [l/min]=calculated flow Q N [l/min]=rated flowD p [bar]=actual valve pressuredropD p N [bar]=rated valve pressuredropQ Q p p NN=∆∆Pressure control mode The afore mentioned flow rate control is superimposed with a pressure limiting control. Both command signals (external flow command signal and limiting pressure command signal) must always be present.The difference between external flow command signal and output signal of the pressure limiting controller results in a spool position command signal. This output signal is zero as long as the actual pressure is smaller than the limiting pressure command value.If the actual pressure value exceeds the limiting pressure command value, the pressure limiting controller reduces the spool position command signal until the actual pressure value equals the limiting pressure command value.If instead of pressure limiting a pressure control has to be installed, the external flow command signal must be selected that high, so that the limiting function actually occurs.This is necessary because the pressure limiting controller can only reduce the spool position command. The external flow command signal should be larger than 30 % of rated signal (see diagrams on page 4).External pilot pressure If large flow rates with high valve pressure drop are required an appropriate higher pilot pressure has to be chosen to overcome the flow forces. An approximate value can be calculated as follows:Q [l/min]=max. flowD p [bar]=valve pressure dropwith Q A K [cm 2]=spool drive area p X [bar]=pilot pressure The pilot pressure p X has to be at least 15 bar above the return pressure of the pilot stage.p QA p X K≥⋅⋅⋅−17102,∆2D691 SeriesProportional Control PQ-ValvesTwo stage withThis catalogue is for users with technical knowledge.

The high pressure recovery of the ServoJet stage (more than 80 % D p at 100 % command signal) provides higher spool driving forces and ensures enhanced spool position The proportional control PQ-Valves D691 Series are dual function valves for 2x2-, 3-, 4- and 5-way applications.The PQ-Valves modulate a fluid flow and control in closed loop a pressure (upper or lower pressure limit). The valves are suitable for pressure control and pressure limiting applications.The control electronics for the spool position and pressure loopsand a pressure transducer are integrated in the valve.For over 15 years MOOG has built PQ-Valves with integrated electronics. During this time more than 30 000 PQ-Valves have been delivered and successfully applied to injection molding, heavy industry, presses and paper processing. The val-ves have proved to be reliable especially when high dynamic performance is required.The valves have been continually developed. With MOOG ’s new ServoJet pilot stage a further step has been taken in the direction of energy saving and robustness.This pilot stage uses the jet pipe principle which for over 8 years has been operating reliably in different MOOG valves.The integrated valve electronics require either 24 Volt DC or a ± 15 Volt DC power supply.The valve series described in this catalogue have suc-cessfully passed EMC tests required by EC Directive.

美国MOOG伺服阀伺服阀的工作原理及作用
美国MOOG伺服阀，伺服阀的工作原理及作用1、电液伺服阀主要用于电液伺服自动控制系统,其作用是将小功率的电信号转换为大功率的液压输出,经过液压执行机构来完成机械设备的自动化控制.伺服阀是一种经过改动输入信号。
依据输入信号的方式不同，分为电液伺服阀和机液伺服阀。
电液伺服阀既是电液转换元件，又是功率放大元件，它的作用是将小功率的电信号输入转换为大功率的液压能（压力和流量）输出，完成执行元件的位移、速度、加速度及力控制。
液压泵的输出压力是指液压泵在实践工作时输出油液的压力，即泵工作时的出口压力，通常称为工作压力，其大小取决于负载。
电液伺服阀通常由电气—机械转换安装、液压放大器和反应（均衡）机构三局部组成。
反应战争衡机构使电液伺服阀输出的流量或压力取得与输入电信号成比例的特性。
压力的稳定通常采用压力控制阀，比方溢流阀等。
2.细致材料：典型电---气比例阀、伺服阀的工作原理电---气比例阀和伺服阀按其功用可分为压力式和流量式两种。
压力式比例/伺服阀将输给的电信号线性地转换为气体压力；流量式比例/伺服阀将输给的电信号转换为气体流量。
美国威格士VI CKERS柱塞泵由于气体的可紧缩性，使气缸或气马达等执行元件的运动速度不只取决于气体流量。
还取决于执行元件的负载大小。
因而准确地控制气体流量常常是不用要的。
单纯的压力式或流量式比例/伺服阀应用不多，常常是压力和流量分离在一同应用更为普遍。
电---气比例阀和伺服阀主要由电---机械转换器和气动放大器组成。
但随着近年来低价的电子集成电路和各种检测器件的大量呈现，在1电---气比例/伺服阀中越来越多地采用了电反应办法，这也大大进步了比例/伺服阀的性能。
电---气比例/伺服阀可采用的反应控制方式，阀内就增加了位移或压力检测器件，有的还集成有控制放大器。

MOOG(穆格)D633、D634系列伺服阀是MOOG公司最新研制成功的新型电液伺服阀，目前已由MOOG GmbH(德国)公司进行批量生产。它是一种直接驱动式伺服阀，简称DDV(Direct Drive Servo Valve的缩写)，油口与安装尺寸D633按NG6(Cetop 3),D634按NG10(Cetop 5)，用集成电路实现阀芯位置的闭环控制，阀芯的驱动装置是永磁直线力马达。对中弹簧使阀芯保持在中位，直线力马达克服弹簧的对中力使阀芯在两个方向都可偏离中位，平衡在一个新的位置，这样就解决了比例电磁线圈只能在一个方向产生力的不足之处。阀芯位置闭环控制电子线路与脉宽调制（PWM）驱动电子线路固化为一块集成块，用特殊的连接技术固定在伺服阀内，因此D633、D634系列伺服阀无需配套电子装置就能对其进行控制。

The pilot valve produces differential pressure in its control ports. This pressure difference results in a pilot flow which causes main spool dis-placement.The position transducer which is excited via an oscillator measures the position of the main spool (actual value, position voltage).This signal then is demodulated and fed back to the control amplifier where it is compared with the command signal. The control amplifier drives the pilot valve until the error between command signal and feedback signal is zero. Thus, the position of the main spool is proportional to the electrical command signal.Q Q p p NN=∆∆p 2,510QA pX -2K≥⋅⋅∆The actual flow depends on the electrical command signal and the valve pressure drop, and may be calculated using the square root function for a sharp-edged orifice.The flow value Q calculated in this way should not exceed an average flow velocity of 30 m/s in ports P, A, B and T.Q [l/min]=calculated flow Q N [l/min]=rated flowD p [bar]=actual valve pressuredropD p N [bar]=rated valve pressuredrop2If large flow rates with high valve pressure drops are required, an appropriate higher pilot pressure has to be chosen to overcome the flow forces. An approximate value can be calculated as follows:Our quality management system is certified in accordance with DIN EN ISO 9001.This catalogue is for users with technical knowledge. To ensure that all necessary characteristics for function and safety of the system are given, the user has tocheck the suitability of the products described here.In case of doubt please contact MOOG.The flow control servovalves D791and D792 Series are throttle valves for 3-way and preferably 4-way applications. These three stage servovalves have been especially developed for such demanding applications where high flow rates and at the same time extreme dynamic performance require-ments must be met. The design of these valves is based on the well known D079 Series. The inte-grated electronics has been replaced by a new design applying SMD technology. The valves areoffered with pilot valves of D761or D765 Series, optional standard response or high response versions are available.

ELECTROHYDRAULIC VALVE CUT-AWAYFigure 1 Moog Series .760KUpper Polepiece Flexure Tube FlapperLower Polepiece Feedback WireInlet OrificeMagnet Coil Armature Nozzle SpoolControl Port BTank Control Port A PressureFilter5. HYDRAULIC SYSTEM PREPARATIONT o prolong servovalve operational life and to reduce hydraulic system maintenance, it is recommended that the hydraulic fluid be kept at acleanliness level of ISO DIS 4406 Code 16/13 maximum, 14/11 recommended. The most effective filtration scheme incorporates the use of a kidney loop or “off-line” filtration as one of the major filtration components. The filter for the “off-line” filtration scheme should be a B 3≥75 filter for maximum effectiveness.U pon system startup, and prior to mounting the servovalve, the entire hydraulic system should be purged of built-in contaminating particles by an adequate flushing. The servovalve should be replaced by a flushing manifold and the hydraulic circuit powered up under conditions of fluid temperature and fluid velocity reasonably simulating normal operating conditions. New system filters are installed during the flushing process whenever the pressure drop across the filter element becomes excessive. The flushing processes should turn over the fluid in the reservoir between fifty to one hundred times.T o maintain a clean hydraulic system, the filters must be replaced on a periodic basis. It is best to monitor the pressure drop across the filter assembly and replace the filter element when the pressure drop becomes excessive. In addition to other filters that are installed in the hydrauliccircuit, it is recommended that a large capacity, low pressure ß3≥75 filter be installed in the return line. This filter will increase the interval between filter element replacement and greatly reduce the system contamination level.6. INSTALLATIONT he Moog .760K Series Industrial Servovalve may be mounted in any position, provided the servovalve pressure, control, and tank ports match respective manifold ports. The mounting pattern and port location of the servovalve is shown on figure 4. The servovalve should be mounted with 5/16-18 x 1.75 inch long, socket head cap screws. Apply a light film of oil to the screw threads and torque to 96 inch pounds. Wire mating connector for desired coil configuration and polarity. Thread connector to valve.7. MECHANICAL NULL ADJUSTMENTI t is often desirable to adjust the flow null of a servovalve independent of other system parameters. The “mechanical null adjustment” on the Moog .760K Series servovalve allows at least ±20% adjustment of flow null.T he “mechanical null adjustor” is an eccentric bushing retainer pin, located above the “tank” port designation on the valve body (see Figure 2) which, when rotated, provides control of the bushing position. Mechanical feedback elements position the spool relative to the valve body for a given input signal. Therefore, a movement of the bushing relative to the body changes the flow null.Adjustment ProcedureUsing a 3/8 inch offset box wrench, loosen the self-locking fitting until the null adjustor pin can be rotated. (This should usually be less than 1/2 turn). DO NOT remove self-locking fitting. Insert a 3/32 inch Allen wrench in null adjustor pin. Use the 3/32 Allen wrench to rotate the mechanical null adjustor pin to obtain desired flow null. Torque self-locking fitting to 57 inch lbs.Note: Clockwise rotation of null adjustor pin produces flow from port P to port B.3. ELECTRICAL INFORMATION AND INTRINSICALLY SAFE CIRCUIT SAFETY PARAMETERSa.A wide choice of coils is available for a variety of rated currentrequirements. The torque motor coil leads are attached to the connector so external connections can provide series, parallel or single coil operation. The valves are equipped either with an MS type connector or with pigtail leads for electrical wiring. Refer to installation drawings of the specific model for details. Servovalve coils should be driven with current to provide consistency throughout the temperature range.b.The .760K valves are approved for intrinsically safe protection per EN IEC 60079-0 : 2018, EN 60079-7 : 2015, and EN 60079-11 : 2012 for ATEX, and IEC 60079-0 : 2017, IEC 60079-7 : 2017, and IEC 60079-11 : 2011 for IECEx. The approved safety parameters are listed in the following table for all the coils used by .760K series. Coil number is marked on the valve nameplate.Coil ConfigurationMarkingU i (MAX) I i (MAX)G4220-031 (single, series, parallel) Ex ia IIB T4 12 V 120 mA G4220-051/098 (single, series, parallel) Ex ia IIB T4 12 V 240 mA G4221-001 G4220-042 (single) Ex ia IIC T4 16 V 160 mA G4221-001 G4220-042 (single) Ex ia IIC T4 24.4 V 85 mA G4220-031 (single, parallel) Ex ia IIC T4 30 V 26 mA G4220-031 (series)Ex ia IIC T4 30 V 18 mA G4220-051/098 (single, parallel) Ex ia IIC T4 30 V 19 mA G4220-051/098 (series) Ex ia IIC T4 30 V 12.7 mA G4220-042 (single) Ex ia IIC T4 30 V 37 mA G4220-042 (parallel) Ex ia IIC T4 30 V 20 mA G4220-042 (series) Ex ia IIC T4 30 V 10 mA G4221-001 (single) Ex ia IIC T430 V28 mAc. The .760K valves are approved for non-incendive operation for supply current not to exceed 50 mA dc.d.When making electric connections to the valve, appropriate measures must be taken to ensure that locally different earth potential do not result in excessive ground currents. When barriers are required for the hazardous location, hazardous area (field) wiring must meet the requirements of the barrier manufacturer. All barriers must be mounted and installed in compliance with the barrier manufacturer’s requirements. Twisted pairs of 18-20 gage wire are recommended. If shielded wire is used, connect shield wire to earth ground only at the barrier strip.4. SPECIAL CONDITIONS FOR SAFE USE Because the enclosure of the apparatus is made of aluminum, if it ismounted in an area where the use of category 1 G apparatus is required, it must be installed such that even in the event of rare incidents, ignition sources due to impact and friction sparks are excluded. When the electrohydraulic servovalve is used in an application for type of explosion protection intrinsic safety “i”, the appropriate box on the data label must be scored. When the electrohydraulic servovalve is used in an application for type of explosion protection “n”, the appropriate box on the data label must be scored. After use in an application for type of explosion protection “n”, the servovalve cannot abe safely used in a intrinsically safe application. The screwed cable connector may only be disconnected when the circuit is de-energized or when the location is known to be non-hazardous. When used at an ambient temperature ≥70°C, heat resistant cable must be used with a continuous operating temperature in accordance with the application. When the electrohydraulic servovalve is used in type of protection “n” or “ec”, the equipment shall only be used in an area of not more than Pollution Degree 2, as defined in IEC 60664-1. The cable gland shall be installed such that impact is not possible. When the electrohydraulic servovalve is used in type of protection “n” or “ec”, the user shall provide additional clamping of the cable to ensure that pulling is not transmitted to the terminations.Mechanical Null AdjustmentPotential TroubleServovalve does not follow input command signal. (Actuator or components are stationary or creeping slowly).High threshold. (Jerky, possible oscillatory or “hunting” motion in closed loop system).Poor response. (Servovalve output lags electrical command signal).High Null Bias, (High input currentrequired to maintain hydraulic cylinder or motor stationary).Probable Cause1. Plugged inlet filter element.1.

多级阀的工作原理
主阀芯的位置闭环控制是由集成电子装置来实现的。 一个电气指 令信号 （ 用来设定流量 ） 作用于集成电路位置控制器并由此来驱 动阀线圈。 位置传感器通过振荡器测出主阀芯的实际位移 （实际 值， 位移电压） 。 此信号被解调并反馈至控制器与指令信号相比较。控制器驱动先 导阀偏转从而使主阀芯产生位移，直至指令信号与反馈信号之间 的偏差为零。由此得到主滑阀的位移与指令电信号成正比。
阀的体积流量计算
阀的实际体积流量取决于阀芯位移和阀口两端节流边的压降。 在 100% 指令信号（即 +10 V DC = 100% 阀口全开）、额定压降 ∆pN = 每节流边 5 bar (75 psi) 时，阀的体积流量定义为额定流量 QN。对于非额定压降，在一个特定的指令信号下，阀的体积流量 则与阀的锐边节流口的压降的平方根成正比。 Q [l/min] = 计算出的流量 = 阀的实际压降 = 阀的额定压降

故障保险设计可使滑阀在短路，失电或者油源失压情况下通过 对中弹簧和座阀使主阀芯处于可未知的位置。 单级或二级先导阀控制。
伺服射流管 SERVOJET® 先导阀的工作原理
伺服射流管先导阀主要由力矩马达、射流管和接收器组成。当线 圈中有电流通过时，产生的电磁力使射流管喷嘴偏离中位。这个 偏置和特殊形状的喷嘴设计使得当聚集喷射的液流射向一侧的接 收器造成先导阀的接收器产生压差。此压差直接导致阀芯两侧驱 动力产生差导，推动主阀芯产生位移。先导阀的泄漏油通过喷嘴 环形区域处的排出通道流回回油口。
阀的优点
超大流量阀体流道设计，并可选择使用 X 和 Y 口进行先导级外 控、外泄。 减小了 D662 – D665 阀芯的驱动面积，从而具有下列优点： - 改善了动态响应 - 使较小的先导级流量也能驱动阀芯快速运动。
功率级滑阀由单级或二级先导阀驱动。因此，D660 系列比例阀 有二级和三级构造两种形式。二级比例阀主要运用在小信号时要 求具有较高分辨率和较高动态响应的场合中。而三级比例阀适用 于在较大指令信号下有较高动态响应要求的场合。我们的伺服比 例控制阀结合了快速响应的先导级、合理的滑阀驱动面积和集成 电路板的功能，因此该产品拥有最佳控制性能。

优点和功能
SERVOJET® 伺服射流管先导阀的优点
明显改善了流量利用效率（90% 以上的先导级流量被利用）， 有助于降低能耗，此优点对于使用多台伺服比例阀的机器尤显 突出。
先导级最低控制压力仅 25 bar，此优点使该伺服比例控制阀甚 至可用于如汽轮机控制一类的低压系统中。 伺服射流管先导阀的内置过滤器的的名义间隙均为 200 µm， 因此其寿命几乎是无限的。 基于伺服射流管先导阀比较扁平的压力增益特征使其具有无可 挑剔的工作性能。回路增益的提高使阀具有优异的静态和动态 响应特性，并使控制系统的性能显著提高。
先导级控制压力 pX 必须比先导阀的回油压力至少高 25 bar (360 psi)。 4 穆格 • D660 系列
