Product Overview
The MOOG 0761-3004B / H30JOGH4VPL is a high-performance, two-stage electrohydraulic servo valve engineered by Moog, the global benchmark in precision motion control. Operating on a torque-motor pilot stage with a spool-type second stage, this valve converts low-power electrical current signals into precise, high-response hydraulic flow and pressure outputs. It serves as the critical control element in closed-loop industrial and aerospace-grade hydraulic systems, delivering exceptional dynamic response, minimal hysteresis, and repeatable metering accuracy for demanding position, velocity, and force control applications.
