Rotork's Variable Speed Drive ensures the operation of part-turn valves, globe valves, and dampers. Fail in-place and failsafe open/close options are avaiable. The drive has a positional accuracy of less than 0.1% and a repeatability of less than 0.1% of full stroke. A wide range of status, alarm, and input/output signals can be configured with parameters stored in nonvolatile memory. Linear thrust outputs range from 2,000 to 100,000 lbs and rotory torque outputs range from 2,000 to 300,000 lbf-in.
The drive's control enclosure is available with NEMA 4x and NEC Class 1, Division 1 ratings. It can be mounted on the actuator or remotely at a distance of up to 300 ft from the valve.
