MOOG D634‑319C Servo Valve

Product Overview

The MOOG D634‑319C is a direct‑acting electro‑hydraulic servo valve of D634 DDV series. Driven by permanent‑magnet linear force motor, it converts analog electrical control signals into precise hydraulic flow output, without pilot‑oil supply requirement. It accurately regulates flow, pressure, position and velocity for hydraulic actuators, widely adopted for high‑precision closed‑loop motion control in heavy‑duty industrial hydraulic systems.

Product Advantages

✅ Direct‑acting pilot‑free structure: No pilot oil required, dynamic performance keeps stable regardless of system pressure fluctuation ✅ Integrated closed‑loop spool‑position feedback: Low hysteresis, high resolution and outstanding repeatability for accurate control ✅ Spring‑centered fail‑safe design: Spool returns to neutral position upon power loss or cable damage, improving equipment safety ✅ High‑output linear force motor: Strong anti‑jamming capacity, adapts to harsh polluted hydraulic oil environment ✅ Low power consumption at hydraulic zero point, energy‑saving for continuous operation condition ✅ ISO 4401‑05 standard mounting interface, easy installation and interchangeability with standard hydraulic manifolds ✅ IP65 housing rating, reliable performance under workshop dust and splash conditions ✅ 24 VDC PWM integrated electronics, compatible with mainstream industrial analog control signals
