System compatibility

D072-022A belongs to MOOG D072 series two-stage 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

D072-022A adopts torque motor nozzle flapper two-stage structure.It converts differential current command signal into proportional hydraulic flow,high control precision and fast response.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

‑Threaded circular electrical connector

‑Valve laser marking label

Feature

MOOG D072 series two-stage servo valve,high accuracy,low hysteresis,excellent dynamic performance.Typical faults:zero drift,internal leakage,nozzle blockage,torque 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 torque motor coil.

Product Brief

D072-022A is MOOG D072 series two-stage electro-hydraulic servo valve.With nozzle flapper pilot stage,high precision,compact hydraulic control component for industrial closed-loop servo system overhaul and replacement.
