Rotork: Variable Speed Drive

ROTORK VSD Photo FNLRotork’s Variable Speed Drive (VSD) is a simple, versatile, and reliable solution for modulating valve control. The variable speed control provides a high response rate and stable control with minimal overshoot. Rotary and linear versions enable the operation of part-turn valves, globe valves, and dampers. Fail in-place or failsafe open/close options are available.

Positional accuracy is < 0.1% with repeatability < 0.1% of full stroke. A wide range of status, alarm, and input/output signals can be configured with parameters stored in non-volatile memory.

Linear thrust outputs are from 2,000-100,000 lbs and rotary torque outputs are from 2,000-300,000 lbf-in.

The Rotork VSD control enclosure is available with NEMA 4X and NEC Class 1, Division 1 ratings. It can be mounted on the actuator or remotely up to 300 feet from the valve. A 120Vac power supply is required.
