Company Profile
Product Details
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.
