Product Overview
The MOOG D691Z2701G / 080FUAEAVVS2N is a high-performance servo proportional valve from the MOOG D691 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 pilot stage that drives a precision spool main stage, delivering exceptional dynamic response, minimal hysteresis, and superior flow metering accuracy. The valve is configured with integrated electronics (080FUAEAVVS2N configuration) providing factory-set spool position feedback and closed-loop control for consistent, repeatable performance. As a critical control element in hydraulic systems, it regulates flow direction and magnitude proportional to an electrical command signal, enabling precise velocity, position, and force control of actuators in closed-loop hydraulic circuits.
