Product Overview

The MOOG D920-141 / R08KB910HXYX is a high-performance servo proportional valve from the MOOG D920 series, engineered for precise electrohydraulic control in demanding industrial and motion-control systems. Utilizing MOOG’s proven two-stage servo valve architecture, this unit features a torque-motor pilot stage that hydraulically actuates a precision-ground main spool, delivering infinitely variable flow control proportional to the electrical input signal. The D920 platform is renowned for its fast dynamic response, high resolution, and excellent repeatability, making it a critical control element in closed-loop position, velocity, and force control applications. The R08KB910HXYX designation defines the specific spool configuration, rated flow, and electrical interface of this factory-configured variant.
