Fixed orifice, bypass/restrictive, priority, flow control valveCapacity:6 gpm (23 L/min.)Functional Group:Products : Cartridges : Flow Control : 3 Port : Fixed Orifice, Bypass/RestrictiveModel: FRCAProduct DescriptionBypass/restrictive, fixed-orifice, priority flow controls take an input flow at port 1 and use it to satisfy the priority flow at port 3. If the input flow exceeds the priority flow requirement, the excess is bypassed out port 2. The bypass flow may be used in a secondary circuit.Technical FeaturesCustomer must specify a flow rating. Factory set flow ratings are within +/- 10% of the requested setting.Pressure at the bypass port (port 2) may exceed pressure at the priority port (port 3).Both priority and bypass flow are usable up to the system operating pressure.The sharp-edged orifice design minimizes flow variations due to viscosity changes.Priority remains relatively constant regardless of variation in input flow.A tuneable adjustment control option provides up to +/- 25% variation from the nominal factory pre-set flow. Adjustment is done with +/- 3 turns of the adjust screw. Screw in (CW) to increase flow.Bypass flow is not available until priority flow requirements are satisfied.Incorporates the Sun floating style construction to minimize thepossibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.DownloadFRCA-XAN$42.60Recommended List PriceControl Setting Range Seal Material Material/CoatingModifierPreferred OptionsL Tuning Adjustment +8.00 Standard OptionsK Handknob +14.00 X Not Adjustable +0.00Preferred OptionsA*Replaceable Orifice .1 -6 gpm (0,4 - 23 L/min.)+0.00Preferred OptionsN Buna-N +0.00Standard OptionsV Viton +5.00Preferred OptionsNo modifier (standard materialwith no special coating)Special Options/AP Stainless Steel, PassivatedControl: L +202.40Control: C +225.40Our corrosion resistant productline is growing!

They are used to maintain a flow constant virtually independent of pressure and temperature.The valves basically consist of the housing (1), orifice bush (2), pressure compensator (3) with optional stroke limiter (3.1), check valve (4), adjustment element (5) for type 2FRM.. as well as a rack and pinion actuator (6), directional valve (7) and actual value potentiometer (8) for types 2FRH... and 2FRW...The flow from port A to port B is throttled at the orifice (9). On type 2FRM.. the throttling area is adjusted by rotating the cur-ved pin (10) mechanically by means of the adjustment element (5), for types 2FRH.. and 2FRW.. hydraulically via a rack and pinion actuator (6), which is controlled by a built-on electrically operated directional valve (7). The control speed can be set by means of throttle check valves (6.3 and 6.4). In order to limit the required actuating range, the rack and pinion actuator (6) is fitted with adjustable stroke limiters on both ends (6.1 and 6.2). In order to to maintain the flow across the orifice (9) constant, a pressure compensator is connected upstream of the orifice (3).The flow is maintained largely independent of temperature due to the orifice design.Free return flow from port B to port A is via the check valve (4).In order to permit the orifice position in valve types 2FRH.. and 2FRW.. to be continuously monitored, an actual value potentio-meter (8) can be fitted. Suitable electrical control components are available for electrical command value pre-selection. The flow is only controlled from A to B. In order to control the flow in both directions a rectifier sandwich plate type Z4S (supply and return) can be installed under the flow control valve.Preferred types (readily available)Section X–XTypeMaterial No.2FRM 10-3X/10L R9004248872FRM 10-3X/10LB R9004232502FRM 10-3X/16L R9004232512FRM 10-3X/16LB R9004232522FRM 10-3X/25L R9004232552FRM 10-3X/25LB R9004232562FRM 10-3X/50L R9004202862FRM 10-3X/50LBR900423261TypeMaterial No.2FRM 16-3X/100L R9004249052FRM 16-3X/100LB R9004202872FRM 16-3X/160L R9004249062FRM 16-3X/160LB R9004249022FRM 16-3X/160L V R9004277772FRM 16-3X/60L R9004232712FRM 16-3X/60LBR900424903Function, sectionTechnical data (for applications outside these parameters, please consult us!)GeneralWeight NS 10NS 16Type 2FRM kg 5.611.3Type 2FRH kg9.214.9Type 2FRH..P kg10.316Type 2FRW kg11.317Type 2FRW..P kg12.418.1Rectifier sandwich plate kg 3.08.1Installation Type 2FRM InstallationTypes 2FRH and 2FRW Actuator horizontal (rack and pinion)Pressure fluid Mineral oil (HL, HLP) to DIN 51 524 1);Fast bio-degradable pressure fluids to VDMA 24 568(also see RE 90221); HETG (rape seed oil) 1);HEPG (polyglycole) 2); HEES (Synthetic ester) 2);other pressure fluids on requestAmbient temperature range NBR seals°C–30 to +80 (–30 to +50 for type 2FRW)FKM seals°C–20 to +80 (–20 to +50 for type 2FRW)Pressure fluid temperature range NBR seals°C–30 to +80FKM seals°C–20 to +80Viscosity range mm2/s10 to 800ISO code cleanliness class Maximum permissible degree of contamination of the pressurefluid is to ISO 4406 (C) class 20/18/15 3)1)Suitable for NBR and FKM seals2)O nly suitable for FKM seals3) The cleanliness class stated for the components must beadhered too in hydraulic systems.

流量调节阀中文

操作说明1.流速（探测）元件：压差控制器（3）处于正常开启状态并且受孔板（5）探测到的压差变化而控制。

压差上升，控制器趋向于“关”（3）；压差减小，控制器趋向于“开”（3）。

这使得主阀盖压力发生变化，并使主阀在“开”或“关”之间变化以维持相对恒定的流速。

压差控制器（3）调节：沿顺时针方向旋转调节螺钉可以增大流速。

2.元件操作说明：开关元件：开关元件（4）由一个与主阀板连接的阀杆驱动。

当主阀接近全开或全关时，可以通过调节开关来驱动单刀双掷开关。

当主阀开始开启或关闭时，弹簧开关操纵杆被释放，使开关回到常规位置。

3.附件操作说明：附件A （过滤器）装置阀门进口的单向过滤器用来防止杂质微粒进入导向系统。

附件B （截断阀）阀门B1和B2用来切断主线压力向控制系统的传递。

正常操作时，这些阀门必须开启。

附件C（关阀速度控制器）CV流量控制器主要控制主阀关闭速度。

顺时针选准调节杆可以降低关阀速度。

附件G（止回阀）当出口压力大于入口压力时，止回阀（G2）开启，使出口处的高压关闭主阀，止回阀（G1）关闭，防止阀体外的液体流进入口阀。

附件Q（快速接头）快速接头便于压力仪表与主阀连接及拆卸。

附件S（开发速度控制器）CV流量控制器主要控制主阀关闭速度。

顺时针选准调节杆可以降低关阀速度。

附件T（泄压装置）泄压控制器只与止回构件（附件G）配合使用，当出口要了超过入口压力并且压差达到设定值时，泄压装置打开，使出口压力降至入口正常压力。

附件Y（Y-过滤器）Y-过滤器安装在导向器传入线上，防止杂质微粒进入控制系统。

过滤器滤网必须定期清理。

4.合理操作检查清单（1）上下游系统阀组开启。

（2）排净阀体和导向系统的所有高点气体。

（3）建议定期清理Y-过滤器。

（4）CV流量控制器至少开启4圈。

（5）止回阀B1、B2、G3、开启。

100-34 液压阀说明100-34 海托尔阀是自动控制阀的主阀，它是一个液压驱动的球形或锥形隔板控制阀。

显然，T值越大，节流阀的刚性就越好，负载变化引起流量的波动就越小，即通过节流阀的流量较稳定。影响刚性T的因素有：
① 对同一节流阀，当Δp相同时，节流口的开度越小，通过节流口的流量越小，刚性越好，流量越稳定，即节流阀的刚度与流量成反。
a

② 对于同一个节流阀，阀口开度一定时，压力差Δp越大，T值也越大，流量也越稳定，图5-56中曲线Δp越大曲线越平缓。

当节流阀调整好后（阀口过流面积调定），我们希望通过节流阀的流量较稳定，使执行元件获得一个相对稳定的运动速度，而实际上，由于种种因素的影响，流量是不可能恒定的。影响流量稳定的主要因素有以下几种。

1、刚性
在用节流阀调节执行元件的运动速度时，往往会因负载的波动引起阀前后压力差的变化，此时即便节流阀的过流面积不变，经节流口的流量也会发生变化，即流量不稳定。节流阀的刚性是指阀开口面积一定时，节流阀前后压力差Δp的变化量与流经阀的流量Q变化量之比，用T表示。

Ventable, fixed orifice, bypass/restrictive, priority, flow control valve Capacity:25 gpm (95 L/min.)Functional Group:Products : Cartridges : Flow Control : 4 Port : Fixed Orifice, Bypass/Restrictive, Ventable Model: FVEAProduct DescriptionVentable, bypass/restrictive, fixed-orifice, priority flow controls take an input flow at port 1 and use it to satisfy the priority flow at port 3. If the input flow exceeds the priority flow requirement, the excess is bypassed out port 2. The bypass flow may be used in a secondary circuit. A vent port (port 4) allows these valves to be controlled remotely.Technical FeaturesCustomer must specify a flow rating. Factory set flow ratings are within +/- 10% of the requested setting. The sharp-edged orifice design minimizes flow variations due to viscosity changes.Both priority and bypass flow are usable up to the system operating pressure. A tuneable adjustment control option provides up to +/- 25% variation from the nominal factory pre-set flow. Adjustment is done with +/- 3 turns of the adjust screw. Screw in (CW) to increase flow.Priority remains relatively constant regardless of variation in input flow. Using a pressure control on port 4 will limit the pressure at the priority port (port 3). If pressure on the bypass port (port 2) exceeds the setting of the pressure control, priority flow will be shut off and all the flow will go out the bypass port.Bypass flow is not available until priority flow requirements aresatisfied, except when the valve is vented. When port 4 (vent) is open,all flow diverts to port 2 if pressure at port 1 (inlet) is 150 psi (10,5bar) or higher.Maximum pressure at port 3 should be limited to 3000 psi (210 bar).Pressure at the bypass port (port 2) may exceed pressure at the priority port (port 3).

详解流量控制阀

流量控制阀流量控制阀是通过改变节流口通流断面的大小，以改变局部阻力，从而实现对流量的控制。

流量控制阀有节流阀、调速阀和分流集流阀等.节流阀1-阀体2—阀心3—调节螺钉4—阀套5—阀心上的螺旋断面6—阀口阀套上的窗口W与阀心上的螺旋曲线S之间的相对运动，形成了可变通流断面面积，实现了对流量的控制.改变节流口通流断面的大小，在一定的压差下,可以控制节流阀的流量。

图形符号：常见的几种节流口形式：针式节流口、三角槽式节流口、转槽式节流口流量特性：节流阀的节流口一定时，其流量随压差的增加而增大。

节流口小到一定值时流量不稳定，出现时断时续现象，称为节流口堵塞（一般0.05L/min）。

不出现堵塞的最小流量叫最小稳定流量.温度变化引起流体粘度变化使流量不稳定（可采用温度补偿装置加以补偿)。

调速阀调速阀是具有恒流量功能的阀类，利用它能使执行元件匀速运动.1—减压阀部分 2-减压口 3—行程限位装置 4—节流阀部分 5-节流口调速阀由两部分组成，一是节流阀部分，二是定差减压阀部分，两部分串联而成。

图形符号：工作原理：将节流阀前后压力p2和p3分别引到定压减压阀阀心下、上两端.当负载压力p3增大即调速阀压差变小时,作用在定差减压阀心的力使阀心下移.减压口增大，压降减少，使p2也增大,从而使节流阀压差△p=p2-p3保持不变；反之亦然，这样就使调速阀的流量不受其压差变化的影响，而保持恒定。

详细原理说明原理说明:通过阀的流量，不随阀前后的压差ΔP(ΔP = P1—P3)而变,而节流阀就无恒流功能。

比较下列曲线可见两者的区别。

调速阀可理解为两个串联节流口组成，Ⅰ为固定节流,Ⅱ为可变节流口。

执行元件工作时,流量Q稳定流过。

外负载F若减小，两个串联节流口的流量Q将会增大。

这时如果能够及时且自动地减小节流口Ⅱ的开度,使流量重回到原来的稳定值Q。

要做到这些就必需自动地保持(P2-P3）不变.Ⅰ节流口用节流阀，Ⅱ节流口用定差减压阀，它可保证节流阀前后压差（P2—P3)不变，因此可实现恒流。

流量控制阀及其应用

• 定量泵节流前后的差异 • (a)无节流；(b)有节流 (a)无节流；(b)有节流无节流
调速阀：调速阀：调速阀能在负载变化的状况下，保持进口、出口压力差恒定。图示调速阀的结构，其动作原理说明如下：
调速阀动作原理说明如下：调速阀
压力油Pl进入调速阀后，先经过定差减压阀的阀口x(压力由p1减至p2〉,然后经过节流阀阀口y流出,出口压力为p3。从图中可以看到,节流阀进出口压力p2、p3经过阀体上的流道被引到定差减压阀阀芯的两端(p3引到阀芯弹簧端,p2 引到阀芯无弹簧端),作用在定差减压阀芯上的力包括液压力、弹簧力。调速阀工作时的静态方程如下: 此时只要将弹簧力固定，则在油温无什么变化时，输出流量即可固定。另外，要使阀能在工作区正常动作，进、出口间压力差要在0.5 －1MPa以上。以上讲的调速阀是压力补偿调速阀，即不管负载如何变化，通过调速阀内部具有一活塞和弹簧来使主节流口的前后压差保持固定，从而控制通过的流量维持不变。另外还有温度补偿流量调整阀，能在油温变化的情况下，保持通过阀的流量不变。
容积调速回路
容积调速回路是通过改变回路中液压泵或液压马达的排量来实现调速的。其主要优点是功率损失小(没有溢流损失和节流损失)且其工作压力随负载变化，所以效率高、油的温度低，适用于高速、大功率系统。 • 按油路循环方式不同，容积调速回路有开式回路和闭式回路两种。开式回路中泵从油箱吸油，执行机构的回油直接回到油箱，油箱容积大，油液能得到较充分冷却，但空气和脏物易进入回路。闭式回路中，液压泵将油输出进入执行机构的进油腔，又从执行机构的回油腔吸油。闭式回路结构紧凑，只需很小的补油箱，但冷却条件差。为了补偿工作中油液的泄漏，一般设补油泵，补油泵的流量为主泵流量的10%～15%。压力调节为3×105～10×105Pa。容积调速回路通常有三种基本形式：变量泵和定量液动机的容积调速回路；定量泵和变量马达的容积调速回路；变量泵和变量马达的容积调速回路。
