Servovalves and Servo-Proportional Valves are electrohydraulic,
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.
