Product Overview
The MOOG D664-4010 / L05HXBD6NSM2-O is a high-performance servo proportional valve from the MOOG D664 series, engineered for precise electrohydraulic control in demanding industrial and mobile applications. Utilizing MOOG’s proven two-stage servo valve design, this unit features a torque-motor-driven pilot stage that hydraulically actuates a precision spool within the main stage, delivering exceptional dynamic response, high resolution, and minimal hysteresis. The D664 platform is widely recognized for its robust construction, contamination tolerance, and reliable performance in closed-loop position, velocity, and force control systems. With its ISO 4401-compliant mounting interface and integrated spool position feedback, this valve serves as a critical control element in hydraulic systems requiring fast, accurate, and repeatable flow modulation.
