System compatibility

D061-9321 belongs to MOOG D061 series direct drive servo valve.It is widely used in material fatigue test bench,material testing machine and precision hydraulic closed-loop control system.It is complete replacement spare part for hydraulic equipment overhaul.

Function

D061-9321 adopts linear force motor direct drive structure,without nozzle flapper pilot stage.It converts differential current command signal into proportional hydraulic flow,excellent anti-pollution performance.It adjusts oil flow and direction to realize closed-loop regulation of force,pressure and position for industrial hydraulic equipment.

Installation

Mount valve on standard hydraulic manifold.Connect P,T,A,B hydraulic ports and electrical connector.Flush oil circuit before commissioning,complete zero and gain calibration.Take anti-static protection during handling.

Interface

‑Hydraulic P,T,A,B oil ports

‑7 pin threaded circular electrical connector

‑Valve laser marking label

Feature

MOOG D061 series direct drive servo valve,good dirt tolerance,stable dynamic performance.Typical faults:zero drift,internal leakage,force motor coil failure.Inspect oil cleanliness and valve performance regularly.

Diagnostic

Fault phenomenon:output unstable,pressure fluctuation,slow dynamic response,valve no action.Check oil contamination,spool condition and linear force motor coil.

Product Brief

D061-9321 is MOOG D061 series direct drive electro-hydraulic servo valve.No pilot stage design,strong anti-pollution ability,compact high-precision hydraulic control component for industrial closed-loop servo system overhaul and replacement.
