Moog 728 Series Analog Servo Valve

2-stage flow control Mechanical Feedback Valve
Nozzle flapper pilot stage for high dynamics, high resolution and low hysteresis
"Simulator" spool cut minimizes pressure change and "bump" through the zero flow null position
High spool driving forces, rugged design ensures long-life operation
Optional integrated abort manifold/end cap to control motion of actuator to home position in the event of an abort signal
Optional asymmetric flow ratios matched to actuator cylinder requirements
300 l/min
Max pressure 210 bar
