Valves for High-Performance Industrial Applications

A Hydraulic Servo Valves is a device that meters the flow of oil in response to an electrical input signal or command  to control position, velocity, pressure or force in some type of machine or device (usually through a piston or cylinder). Servo Valves are closed-loop control devices that can be single stage, two-stage or three stage designs.

Moog is a leader in designing, manufacturing, and selling high performance hydraulic valve products. With over 60 years experience producing servo and proportional valves for the industrial market, our products are legendary for reliability and accuracy.  Moog valves contain either a mechanical or electrical feedback mechanism.

Designed and built to meet the unique needs of even the most demanding customers, we offer numerous models with a range of sizes, performance characteristics and mounting options. 


Flow Control Valves

Flow control servo valves are designed to produce hydraulic flow output proportional to electrical current input.  Available valve types include:

Pressure and Flow (p/Q) Control

p/Q valves control flow and regulate pressure (upper or lower limiting pressure) and can be used for both pressure regulation as well as applying a pressure-limit.

Our p/Q valves contain integrated digital electronics with optional fieldbus interface.

Servo Valves and Proportional Valves with Special Features

Offerings include servo valves and proportional valves with advanced safety features such as fail-safe and explosion-proof options (e.g. ATEX certification) as well as special performance modifications including customized spool null cuts.

Servo Valves and Proportional Valves Accessories

As part of our approach to providing motion control solutions, Moog provides a wide variety of accessories our customers may need for hydraulic valves. From valve checkers for troubleshooting to mounting manifolds for easy installation on machines to configuration software, Moog’s expertise involves helping you to get running quickly and easily.
