当温度低于-200°C/-328°F时，Habonim建议采用 TFM 1600™或Habonim专用NRG阀座。如果温度更 低，Habonim建议采用PCTFE（KEL-F）阀座。这些 阀座会为客户立即带来实效，包括更低的操作扭矩、更 小的执行器及更有竞争力的产品。 当PCTFE阀座用于高强度17-4PH阀杆（代码M）时必 须采用合适的规格，确保能够承受高工作转矩。石墨/聚 四氟乙烯密封件用于低温系列；PTFE及标准石墨密封 件用于防火应用中。这两种密封件都能够用来提供相同 的阀体/端部密封。
阀门部件，包括阀球、阀杆及初始柔性部分均采用1.5倍额定静压 进行液压测试。然后再拆开阀门，采用超声波浴清洗并去除油 污，使阀非常清洁。所有低温阀在洁净室组装，并采用压力为 80psi的纯氦气进行100%在线测试，以及采用氦探漏仪进行检验 （验收标准为1×10-5立方厘米/秒）。 测试后，将阀端口密封好，并采用聚乙烯袋逐个密封包装好， 确保将阀门完好送到安装地点。 低温测试：在某些情况下，可能需要进行低温阀测试、低温条 件下的运转试验或燃烧试验。

P B T AELECTROHYDRAULIC VALVE CUT-AWAYINSTRUCTIONS HEREIN OR OTHER SPECIFIC WRITTEN DIRECTIONS FROM MOOG WILLINVALIDATE MOOG’S OBLIGATIONS UNDER ITS WARRANTY AND YIELD THE INTRINSICALLYSAFE PROTECTION PERMIT NULL AND VOID. Upper PolepieceFlexure SleeveLower Polepiece Flapper Feedback WireInlet OrificeMagnet(not shown)CoilArmatureNozzleSpoolFilterFigure 1 Moog Series X77XKP B T AInput signal induces a magnetic charge in the armature and causes a deflection of the armature and flapper. This assembly pivots about the flexure tube and increases the size of one nozzle orifice and decreases the size of the other. This action creates a differential pressure from one end of the spool to the other and results in spool displacement. The spool displacement transmits a force to the feedback wire which opposes the original input signal torque. Spool movement continues until the feedback wire force equals the input signal force. 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 coiloperation. 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 X77XK 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 X77XK series. Coil number is marked on thevalve nameplate.Coil Configuration EX Marking U i (MAX) I i (MAX)G4220-031 (single, series, parallel) Ex ia IIB T4 12 V 120 mAG4220-051/098 (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 T4 30 V 28 mAc.The X77XK 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.5. HYDRAULIC SYSTEM PREPARATIONTo prolong servovalve operational life and to reduce hydraulic system maintenance, it is recommended that the hydraulic fluid be kept at a cleanliness 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 ß3≥75 filter for maximum effectiveness. Upon 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. To 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 hydraulic circuit, 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 replacements and greatly reduce the system contamination level.6. INSTALLATIONThe Moog X77XK Series Industrial Servovalve may be mounted in any position, provided the servovalve pressure, piston and return ports match respective manifold ports. The mounting pattern, port location and mounting bolts of the servovalve are shown on Figure 4. Apply a light film of oil to the screw threads and torque to 57 inch-pounds. Wire mating connector for desired coil configuration and polarity. Thread connector to valve.7. MECHANICAL NULL ADJUSTMENTIt is often desirable to adjust the flow null of a servovalve independent of other system parameters. The “mechanical null adjustment” on the Moog X77XK Series servovalve allows at least ±20% adjustment of flow null. The “mechanical null adjustor” is an eccentric bushing retainer pin located above the 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 inch 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.Figure 2Mechanical Null Adjustment10.

and TFM/EPDM).The hard elastomers are supported by a soft elastomer(EPDM).The 2-piece design allows the two elastomers to work independently of each other,thereby reducing tension caused by different thermal properties.Diaphragms are available with3different types of connections:thread, bayonet and button connection.•Threaded connections are used on soft elastomers≥1"•Bayonet connections are used on all hard elastomer≥1/2"•Button connections are used on all small sizes.Material selection:Each application has different working conditions and therefore different demands on the diaphragm.In order to select the most suitable diaphragm for your application,the following factors should be considered:•Working pressure•Application temperatures•Process fluids(product,cleaning liquid,sterilisation,passivation, etc.)Soft elastomer(EPDM)is suitable for most applications and for high working temperatures.Including continuous steam application.Hard elastomers offer the highest possible degree of chemical resistance.Our TFM(PFTE grade)elastomer is a more flexible material and has some of the features of soft elastomer including for example low creep.For further

1. 概述
工作压力Pmax＝420bar；流量Qmax＝80l/min
按照工业标准 ISO1219－1，这些阀属于压力阀。它们可以防止牵拉或推压的负载在负载方向运动时失控地加速运动，或者
防止执行元件以高于设定的（泵侧供油决定的）速度运动。因此，这些元件可以防止油柱的断裂或可能发生的
负载下降时通过 S 口从另一侧（执行元件的进油路）开启 V→F 方向的通路。
