Hydraulic servo valves, as a type of flow measurement device, can control position, speed, pressure, or force in certain types of machines or equipment (typically through pistons or hydraulic cylinders) based on electrical input signals or commands. Servo valves are closed-loop control devices and can be designed in single-stage, two-stage, or three-stage configurations.
MOOG is a leader in the design, manufacture, and sale of high-performance hydraulic valve products. With over 70 years of experience producing servo and proportional valves for the industrial market, our products are renowned for their reliability and accuracy. MOOG valves feature mechanical or electrical feedback mechanisms.
Even for the most demanding customers, our designed and manufactured products can meet unique requirements. We offer a wide range of models, including various sizes, performance characteristics, and mounting options.
Flow Control Valves
Flow control servo valves are designed to generate hydraulic flow output proportional to the input electrical signal. Available valve types include:
With integrated digital circuits and optional fieldbus interfaces
With analog interfaces integrated into circuits
With analog interfaces without integrated circuits
Pressure and Flow (p/Q) Control
p/Q valves can control flow, regulate pressure (upper or lower limits), and are also used for pressure regulation and applying pressure limits. MOOG's p/Q valves are equipped with integrated digital circuits with optional fieldbus interfaces.
Digital Control and Axis-Controlled Servo Valves
MOOG's digital and axis-controlled servo valve series can customize valves and adjust software according to requirements, meeting specific customer needs for machine flexibility, production, and maintenance. Explosion-proof models are certified by ATEX, IECEx, and FM, suitable for potentially hazardous environments.
Servo Valves and Proportional Valves with Special Features
The servo and proportional valves we offer feature advanced safety functions, such as fail-safe options and explosion-proof selections (e.g., ATEX certification), as well as special performance modifications (including customized valve core zero openings).
Servo Valves and Proportional Valves Accessories
MOOG provides a variety of hydraulic valve accessories that customers may need, which is one of the ways we offer motion control solutions. From valve testers for troubleshooting to convenient oil blocks for installation on machines, and software for configuring technical parameters, MOOG's expertise will help you achieve fast and efficient operation.
