English Description
MOOG 351A7620P0102 (original factory model 743F003A) is a high-performance two-stage electro-hydraulic servo valve of MOOG 743 series. Adopting a nozzle-flapper mechanical feedback structure and 4-way flow control design with a three-coil torque motor, it features excellent fault tolerance and operational stability. Equipped with a field-replaceable pilot filter and built-in null adjustment function, the valve has electrical fail-safe protection and a rugged durable structure. With fast response, high control accuracy and strong anti-interference ability, it realizes precise closed-loop control of flow, pressure, position and force in hydraulic systems. It is suitable for long-term continuous operation and high-reliability industrial scenarios, serving as a core precision control component for power generation, high-end test equipment and industrial hydraulic systems.
