Electrical Feedback Valves

Electrical Feedback Servo Valves and Proportional Valves are closed-loop electro-hydraulic control products for industrial machinery with integrated electronics onboard (OBE) and electrical feedback using a spool position transducer. These valves offer very high accuracy and repeatability in controlling flow and pressure.

Moog offers a wide selection of models with Direct Drive or pilot-operated technologies and many sizes, fail-safe options, and certifications (e.g. ATEX, IECEx). Our engineers work with you to configure the right valves options to ensure it meets your exact performance and application specifications.

Flow Control Valves

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

  • valves with built-in fieldbus interfaces (CANopen, EtherCAT or Profibus DP V1) enable operating parameters to be set, activate the valve and monitor its performance
  • valves with an analog interface and integrated electronics

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.
