SERVO VALVE

Moog Hydraulics Servo Valves
Moog Hydraulics Servo valves meter the flow of oil in response to an electrical output signal or command. They help control position, velocity, pressure or force in a machine or device. Servo valves are closed-loop control devices and can be single, double or triple stage designs. They offer a range of styles, sizes, performance characteristics and mounting options. These include flow control valves, pressure and flow control valves and valves with special features.

Moog Hydraulics Flow Control Servo Valves
Fieldbus Interface: Servo valves containing built-in fieldbus interfaces whichs allows for specific operating parameters to be set and activates the valve and monitor performance.
Integrated Electronics: Servo valves that have the amplifier card and other electronics in the valve body.
Without Integrated Electronics: Servo valves that use the external amplifier cards to convert an input signal into a control current. This drives the servo valve torque motor.
