Product Overview
The MOOG D636-267A-0001 / R04J01F0HXES-00K1A1 is a high-performance servo proportional valve from the MOOG D636 series, engineered for precise electrohydraulic control of flow direction and magnitude in demanding industrial motion systems. Utilizing a closed-loop servo jet pilot stage acting on a robust spool-type main stage, this valve delivers exceptional dynamic response, high resolution, and minimal hysteresis. The D636 platform is a proven two-stage design widely specified for position, velocity, force, and pressure control loops where repeatability and fast settling times are critical. With its integrated spool position feedback and standardized interface, the D636-267A-0001 serves as a direct-fit replacement for OEM servo valve installations in high-cycle industrial machinery.
