Moog Electrohydraulic Products For Precision Motion Control

Servo-Proportional Valves
Moog's Servo-Proportional Valves utilize either ServoJet® or Direct Drive Technology (DDV). ServoJet® piloted valves bring lower internal leakage, improved valve dynamics, greater contamination resistance and improved frequency response to the second stage of Moog proportional valves. DDV and DDV piloted valves utilize a permanent magnet linear force motor design to offer a simple and robust design that is independent of system pressure, has low power dissipation around mid-position and no leakage of pilot valve.

Single or 2-Stage Valves
Electric Feedback Design
Flow or Pressure Control Function
Numerous Failsafe Options

Conforms to ISO4401 port patterns

Electrical and Mechanical Feedback Valves
Moog Mechanical Feedback (MFB) servovalves have been at the heart of closed loop electrohydraulic control systems for decades. In Electrical Feedback (EFB) Servovalves, conventional mechanical feedback has been replaced with electrical feedback using a spool position transducer.

Generally smaller in size than Servo-Proportional Valves
2 or 3-Stage Valves.
Nozzle-Flapper, Jet Deflector, Jet Pipe Torque Motor design.
Conform to ISO 10372 or have non-standard port patterns.

Mechanical Feedback is standard, with optional Electrical Feedback.
