Function

D02HYBD5NSX4-O two-stage jet pipe servo valve converts analog command signal into proportional hydraulic flow.Jet pipe pilot design features strong anti-pollution performance.LVDT sensor feeds back real-time spool position to realize high-precision closed-loop regulation of force,pressure and position.

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

‑11+PE threaded circular electrical connector

‑Valve laser marking label

Feature

MOOG D662 jet pipe servo valve with LVDT spool feedback,low hysteresis,fast response.Typical faults:zero drift,internal leakage,jet pipe damage,electronic circuit 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 built-in amplifier circuit.
