Product Description

Highlight:

Woodward HRT R-DDV® Rotary Direct Drive Servo Valve: A unique and durable design, precisely controlling fluid flow through linear spool motion driven directly by a rotary torque motor.

The Woodward HRT R-DDV®(Rotary Direct Drive Valve)Servovalve is a proven, unique and rugged servovalve design. The limited angle, rotary torque motor drives a valve spool directly through an “eccentric” built into the motor shaft. Rotary operation of the motor results in linear spool motion which modulates fluid flow through the control ports of the valve.

The R-DDV® Servovalve utilizes an integrated electronic controller that is packaged into the torque motor housing. The controller compares spool position, which is monitored by an electronic device within the motor, with the input command signal. The resulting difference generates a current signal that drives the motor to the commanded position. The signal is electronically enhanced to ensure optimum valve performance and linearity.
