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.

Cowan Dynamics: Electro-Hydraulic Linear Valve Actuators

E2H linkedinBannerCowan Dynamics announces the launch of its E2H Series Electro-Hydraulic linear valve actuators. The E2H has been designed from the ground up to pack high performance into the smallest possible installation envelope. All hydraulic components and sensors are integrated into a single compact manifold block that also houses the actuator and integral oil reservoir. The control panel can be mounted directly to the manifold block or installed remotely. This self-contained actuator can be installed either vertically or horizontally and has no external piping. Available for on/off or modulating applications and for a wide range of communication protocols.

Compact: All in one design. No need for a separate hydraulic power unit piping and hoses.
Thrust: Up to 125,000 lbs
Simple: Easy to use touch screen for quick setup and operation.
Operating Temp: -50C to +40C
Data Logging: System records position and time data for valve performance analysis.
Partial Stroke Test: Initiate PST from touch screen or remotely.
Versatile: Fail-last, fail-close or fail-open. Can be mounted in horizontal position.

Cowan Dynamics, established in 1957, has its head office and manufacturing facilities in Montreal, Quebec, a sales office located in Mississauga, Ontario and is represented through a national and international value-added partner network.
