Rotork

Rotork plc, headquartered in Bath, England, is the world's most recognized name in valve actuation and has been manufacturing since 1957. The company pioneered the electric multi-turn actuator with its IQ series, which introduced non-intrusive setting, infrared commissioning and self-diagnostic electronics to plants that could not open actuator covers in hazardous areas. Today Rotork's portfolio spans electric multi-turn and part-turn actuators (IQ, IQT and CMA ranges), fluid power quarter-turn actuators under the GP and GH scotch-yoke and double-acting models, pneumatic piston and diaphragm actuators, and the K-Gear and Skilmatic product families. The company's gearbox and manual override divisions supply worm gear operators that keep large valves operable during power loss. Rotork actuators are found on pipelines, LNG terminals, desalination plants, offshore platforms and nuclear stations, where SIL-rated fail-safe behavior and long maintenance intervals are mandatory. Listed on the London Stock Exchange and organized into three regional divisions covering Europe, the Americas and Asia-Pacific, Rotork combines engineering depth with local commissioning support, which is why many valve OEMs treat it as their default actuation partner.
