System compatibility

760-713A belongs to MOOG 760 series legacy servo valve.It applies to heavy-duty material fatigue test bench,multi-channel simulation loading equipment and medium hydraulic press,widely used in high-precision closed-loop hydraulic control system.It is spare part for legacy hydraulic equipment overhaul.

Function

760-713A is high flow two-stage mechanical feedback servo valve.It adopts polarized torque motor and double nozzle flapper pilot stage,features fast dynamic response and low hysteresis.Mechanical feedback spring realizes spool position feedback,output hydraulic flow proportional to input current signal for accurate 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 high 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

760-713A is MOOG 760 series two-stage mechanical feedback hydraulic servo valve with high flow and compact construction,used for heavy-load hydraulic test and simulation equipment,suitable for industrial hydraulic system maintenance and replacement.Strict oil cleanliness control is required in service.
