trong>62trong> SERIESTWO STAGE SERVOVALVEStrong>62trong> SERIES SERVOVALVESThe trong>62trong> trong>Seriestrong> flow controlservovalves are throttle valvesfor 3- and preferably 4-wayapplications.They are a standardperformance, two-stage designthat covers the range of ratedflows from 2.5 to 20 gpm at1000 psi valve drop.The outputstage is a closed center, fourwaysliding spool.The pilotstage is a symmetrical doublenozzleand flapper, driven bya double air gap, dry torquemotor. Mechanical feedback ofspool position is provided by acantilever spring.The valvedesign is simple and rugged fordependable, long life operation.These valves are suitable forelectrohydraulic position, speed,pressure or force controlsystems with high dynamicresponse requirements.Principle of operationAn electrical trong>comtrong>mand signal(flow rate set point) is appliedto the torque motor coils, andcreates a magnetic force whichacts on the ends of the pilotstage armature.This causes adeflection of the armature/flapper assembly within the flexuretube. Deflection of the flapperrestricts fluid flow through onenozzle which is carried throughto one spool end, displacingthe spool.Movement of the spool opensthe supply pressure port (P) toone control port, while simultaneouslyopening the tank port(T) to the other control port.The spool motion also appliesa force to the cantilever spring,creating a restoring torque onthe armature/flapper assembly.Once the restoring torquebetrong>comtrong>es equal to the torquefrom the magnetic forces, thearmature/flapper assemblymoves back to the neutralposition, and the spool is heldopen in a state of equilibriumuntil the trong>comtrong>mand signalchanges to a new level.In summary, the spool positionis proportional to the inputcurrent and with constantpressure drop across the valve,flow to the load is proportionalto the spool position.VALVE FEATURES➣ 2-stage design with dry torque motor➣ Low friction double nozzle pilot stage➣ High spool control forces➣ High dynamics➣ Low cost design➣ Rugged, long-life design➣ High resolution, low hysteresis➣ Completely set-up at the factoryThe actual flow is dependentupon electrical trong>comtrong>mand signaland valve pressure drop.Theflow for a given valve pressuredrop can be calculated usingthe square root function forsharp edge orifices:Q = Q N∆p∆pNQ [gpm] = calculated flowQN [gpm] = rated flow∆p [psi] = actual valvepressure drop∆pN [psi] = rated valvepressure dropThis catalog is for users with technicalknowledge.To ensure that all necessarycharacteristics for function and safetyof the system are given, the user hasto check the suitability of theproducts described here.

See Table 1.Coil connectionsA four-pin electricalconnector (that mateswith an MS3106R14S-2S)is standard. All four torquemotor leads are availableat the connector so externalconnections can be made forseries, parallel or differentialoperation.ServoamplifierThe servovalve respondsto input current, thereforea servoamplifier that hashigh internal impedance(as obtained with currentfeedback) should be used.This will reduce the effectsof coil inductance and willminimize changes due tocoil resistance variations.ELECTRICALCONNECTIONS(Example with typical trong>62trong> series coils)Parallel trong>Seriestrong> SingleA B C D A B C D A B C DCoil Resistance [Ω] 14 56 28Rated Current [mA] ±100 ±50 ±100Electrical Power [W] .14 .14 .28Connections for Valve Opening A and C (+) A (+), D (-) A (+), B (-)P ➧ B,A ➧T B and D (-) B and C connected or C (+), D (-)Note: Before applying electrical signals, the pilot stage has to be pressured.TABLE 1NominalResistancePer Coil at77ºF (25ºC) ΩRetrong>comtrong>mended Rated Current–mAApproximate Coil Inductance*–HenrysParallel,Differential or SingleCoil Operationtrong>Seriestrong> Coils Single Coils trong>Seriestrong> Coils Parallel Coils28 100 50 0.2 0.8 0.2300 30 15 2 7 2* Measured at 50 Hz.6
