Servo-valves and servo-proportional Valves are electro-hydraulic, continuously acting valves that transform a changing analogue or digital input signal into a step-less hydraulic output (flow or pressure).
The term servo-valve 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’s valves provide precise control of position, velocity, pressure and force.
Moog is a leader in designing, manufacturing, and selling high performance hydraulic valve products. With over 50 years experience producing servo and proportional valves for the industrial market, our products are legendary for reliability and accuracy.
The first product Moog produced was an aerospace servo valve for a missile application. Ever since, Moog has been the recognized leader in servo valve technology expanding into all aerospace applications that require precision motion control.
