System compatibility

B61042-005 is MOOG dedicated torque motor assembly.It matches MOOG D633 / D661 series servo valves,widely used in steam turbine DEH control system,fatigue test bench and precision hydraulic servo system.It is core spare part for servo valve overhaul.

Function

B61042-005 is the pilot stage drive component of two-stage servo valve.Differential current generates electromagnetic torque to deflect the flapper,changes the pressure difference of nozzle chamber and controls the movement of main spool.

Installation

Install torque motor assembly inside servo valve pilot cavity,align flapper and nozzle gap,secure mounting screws.Complete gap adjustment and zero calibration after assembly.Take anti-static protection during handling.

Interface

‑Two pairs of coil wiring terminals

‑Motor laser marking label

Feature

MOOG high linearity torque motor assembly.Typical faults:coil open/short circuit,magnetic attenuation,flapper deformation.Inspect coil resistance during overhaul.

Diagnostic

Fault phenomenon:servo valve no action,zero drift,poor linearity.Check coil resistance and magnetic performance,replace torque motor assembly.

Product Brief

B61042-005 is MOOG servo valve pilot stage torque motor assembly.It is key electromagnetic component for two-stage electro-hydraulic servo valves,used for overhaul replacement in industrial hydraulic servo systems.
