Rotork Actuator Ranges We Supply
| Rotork Range | Type | Where It Goes |
|---|---|---|
| IQ | Electric multi-turn | Gate and globe valves on plant water, steam and process lines |
| IQT | Electric part-turn | Ball, plug and butterfly valves, plus control dampers |
| CK | Modular electric | Retrofits where the existing valve stays and only the actuator changes |
| CVA | Electric modulating | Continuous throttling duty that needs fine position control |
| GP and GH | Pneumatic and hydraulic scotch yoke | High-torque pipeline valves in oil and gas service |
| RC200 | Pneumatic rack and pinion | Opposed and parallel blade dampers and small quarter-turn valves |
| Skilmatic SI | Electro-hydraulic fail-safe | Offshore and topside duty with spring return on power loss |
| Rotork Gears | Worm and bevel gearboxes | Manual override and torque reduction on gastight shut-off dampers |
| Master Station | Network control | Two-wire loop control of large actuator populations from one screen |
Hazardous area versions carry the certification your site requires, so a unit going into a classified zone is picked at the same time as the valve.
See our explosion-proof actuators for that side of the range.
Rotork Actuators for Valve and Damper Control
The duty picks the actuator, not the catalog. Four things set the model.
- Torque or thrust the valve or damper needs at its worst operating point.
- Duty cycle, from open and close service to continuous modulation.
- Fail position on loss of power or air, either fail open, fail close or stay in place.
- Area classification, which sets the enclosure rating and the certification.
Send us the valve or damper schedule and we come back with matched actuators, mounting kits and gearboxes on one quote. We size the same way for fire and smoke dampers and marine and offshore ventilation, where the fail position is part of the life safety design.
