Servo valves and Servo-Proportional Valves are electro hydraulic, continuously acting valves that transform a changing analog or digital input signal into a stepless hydraulic output (flow or pressure)
The term servovalve describes a valve design with bushing spool assembly, characterized by high precision metering edges. The term servo-proportional describes valves with a spool-in-body design.Moog valves provide precise control of position, velocity, pressure and force
