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.。

如何看懂MOOG伺服阀测试报告？电液伺服阀是一个十分精密而又复杂的伺服控制元件，它的性能对整个系统的性能影响很大，因此测试要求十分严格。
每一台维修的伺服阀在出厂前必须严格按照MOOG伺服阀出厂测试标准，每一项测试指标均在规格范围内，满足使用要求之后，方可出厂。
许多小伙伴都对伺服阀的维护保养，报告解读，接线等一系列问题颇感兴趣。
针对大家的需求，穆格售后应用团队将推出一系列知识分享文章，帮助大家更好的了解这个工作中的“好伙伴”。
第一期主题为《如何看懂MOOG伺服阀测试报告？》。
MOOG 伺服阀的种类和型号比较多，但主要的测试项目几乎相同，只是性能指标参数范围有所区别。
我们将分两期，结合典型的机械反馈伺服阀G761和电反馈伺服阀D661维修出厂测试报告，对伺服阀测试项目中的一些专业术语进行解释和说明，方便大家看懂维修测试报告。
单位说明PSI（Pounds per square inch）一种压力计量单位，美国习惯使用psi作单位, 1bar≈14.5psi。
CIS（Cubic inches per second）一种流量计单位, in3/s≈0.984L/min。
G761伺服阀维修出厂测试报告1. 测试报告（表一）说明:1）流量（额定流量）：在伺服阀压降为1000psi（供油压力3000psi，负载压力2000psi）下，对应正负额定电流的负载流量。
此台阀额定流量为63cis，允许的额定流量规格为60-66cis。
2）零偏、滞环、分辨率均可从压力特性曲线和空载流量特性曲线读取。
3）内泄：可以从内泄特性曲线读取。
4）压力零漂：供油压力在2500-3500psi变化时，零偏电流在（-0.40）-0.40mA之间。
5）极性：给线圈电流正负信号时，所对应的流量方向；A+B- LEFT：A+代表A针脚给定指令信号为正，B-代表B针脚给定的指令信号为负，LEFT代表试验台上被测伺服阀B口压力表（若为Right-伺服阀A口压力表）；当针脚A电流信号为“+”时，伺服阀P →B;6）频率响应测试：相位滞后90°时，频率响应在90-500Hz之间，幅值比在 (-8)-2dB之间。
