System compatibility

760-103A belongs to MOOG 760 series legacy servo valve.It applies to material fatigue test bench,simulation loading rig and medium-sized hydraulic press,widely used in high-precision closed-loop hydraulic control system.It is spare part for legacy hydraulic equipment overhaul.

Function

760-103A is two-stage mechanical feedback servo valve with increased rated flow.It adopts torque motor and double nozzle flapper pilot stage,features high resolution and low hysteresis.Mechanical feedback spring realizes spool position feedback,output hydraulic flow proportional to input current signal for precise hydraulic regulation.

Installation

Mount valve on standard hydraulic manifold,tighten mounting bolts to specified torque.Connect hydraulic oil pipeline and electrical control wiring.Complete oil flushing,parameter calibration and performance test before commissioning.Keep clean during handling,prevent oil contamination.

Interface

‑Multi-pin aviation electrical connector

‑Hydraulic P,T,A,B oil ports

‑Valve identification label

Feature

MOOG 760 series medium flow compact servo valve.Typical faults:nozzle blockage,torque motor coil damage,spool sticking,internal leakage.Inspect oil cleanliness and coil resistance before replacement.

Diagnostic

Fault phenomenon:output flow abnormal,zero drift,slow response,no action.Check oil contamination,electrical wiring,coil status and spool condition.

Product Brief

760-103A is MOOG 760 series two-stage mechanical feedback hydraulic servo valve with medium flow and compact structure,applied to precision hydraulic test and loading equipment,suitable for industrial hydraulic system maintenance and replacement.Strict oil cleanliness control is required in service.
