Product Overview
The MOOG D661-4506C / G23JOAA6VSX2HA is a high-performance servo proportional valve from the MOOG D661 series, engineered for precise electrohydraulic control in demanding industrial and motion control systems. Utilizing MOOG’s proven two-stage servo valve architecture, this unit combines a torque-motor-driven pilot stage with a high-capacity spool-type main stage to deliver exceptional dynamic response, precise flow metering, and reliable directional control. The valve responds to analog electrical command signals, proportionally modulating spool position to regulate hydraulic flow and direction with high resolution and minimal hysteresis. It is designed as a direct-fit replacement for OEM MOOG servo valve installations, ensuring dimensional and functional compatibility in closed-loop position, velocity, and force control applications.
