Product Overview
The MOOG D635-662E / R08XB1F0NSM2M is a high-performance servo proportional valve from the MOOG D635 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 pilot stage with a spool-type main stage to deliver fast, accurate, and repeatable flow control proportional to an electrical command signal. The D635 platform is widely recognized for its high dynamic response, low hysteresis, and excellent resolution, making it a preferred choice for closed-loop position, velocity, and force control applications where precise metering of hydraulic flow is critical. The R08XB1F0NSM2M configuration designation defines the specific spool type, rated flow, and electrical interface of the valve, ensuring direct compatibility with MOOG-standard mounting and control systems.
