Key features of the Moog D634-341C Servo Valve:
-
Permanent-magnet linear force motor drive (eliminating the need for pilot oil) for high dynamic response and pressure-independent behavior.
-
Integrated electronics with closed-loop spool position sensing and analog command interface for precise control of flow, position or force.
-
High maximum operating pressure up to 350 bar (5,000 psi) on ports P/A/B, enabling rugged performance in demanding environments.
-
Rated flows at Δp ≈ 35 bar reach up to ~100 L/min (26.4 gpm) for the size 05 D634 series — depending on spool/variant.
-
Spring-centered spool for fail-safe positioning on loss of power, low hysteresis and threshold for improved control fidelity.
