Hydraulic Pump and Valve Supplier – Reliable Solutions for Industrial and Mobile Applications

Key features of the Moog D634‑319C  Servo Valve:

  • Permanent-magnet linear force motor drive (no separate pilot oil stage) for fast response and pressure-independent dynamics.

  • Closed-loop spool position control via integrated electronics, enabling precise and repeatable control of flow, position or force.

  • High operating pressure ratings (port P/A/B up to ~350 bar / 5,000 psi), and rated flows up to 100 L/min (26.4 gpm) at Δp = 35 bar, depending on configuration.

  • Low hysteresis and threshold, low internal leakage, spring-centered spool (fail-safe position) when power is lost.

  • Flexible signal options (±10 V, ±10 mA, 4-20 mA) and standard ISO 4401 mounting (Size 05) for compatibility with industrial systems.
