Moog Directional Control Servovalves with mechanical feedback are throttle valves for 3-, and preferably 4-way application. They have a high performance, two stage design that covers the range of rated flows from 3.8 to 227 l/min (1 to 60 gpm) at 35 bar (1,000 psi) valve drop. The main stage is a closed center, four-way, sliding spool. The pilot is a symmetrical double nozzle and flapper design. The valve design is simple and rugged for dependable, long-life operation.
Servovalves & Servo-Proportional Valves
Directional Control Valves
Directional Control Valves with Fieldbus Interface
Directional Control Valves with Fieldbus Interface
Servovalves with built-in fieldbus interfaces (CANopen, EtherCAT or Profibus DP V1) enable operating parameters to be set, activate the valve and monitor its performance.
Directional Control Valves with Analog Interface
With Integrated Electronics
Servovalves that integrate the amplifier card and associated electronics into the valve body.
Without Integrated Electronics
Servovalves that utilize external amplifier cards to convert an input signal to a control current that drives the servovalve torque motor.
