Moog D661-5046 Pilot-Operated Servovalve for Analog Signals

  • Product Introduction: It is a member of the Moog D661 series of servo valves, which integrates electronics and an analog interface. The valve core slides in the bushing and is hydraulically pilot-controlled. It is designed to meet the most demanding application requirements and can provide high dynamic performance. It can convert electrical signals into hydraulic signals and then control the actuator through a hydraulic control system to achieve precise control of displacement, speed, etc.
