Rotork manufactures electric, pneumatic, hydraulic and electro-hydraulic valve actuators. The Rotork actuator range covers multi-turn, quarter-turn (part-turn) and linear valve automation, so there's a Rotork actuator for almost any isolating, control or fail-safe valve duty across process, water, oil and gas, power and HVAC applications.
A Rotork actuator automates the opening, closing and modulating of valves and dampers that would otherwise be operated by hand. Rotork valve actuators are used for on/off isolation, continuous modulating control and emergency shutdown (ESD), giving remote, repeatable and safe operation of ball, butterfly, gate, globe and plug valves.
The Rotork IQ range is the company's flagship intelligent electric multi-turn actuator, with the latest generation being the IQ3. Rotork IQ actuators feature non-intrusive Bluetooth setup, a double-sealed IP66/68 watertight enclosure, and on-board data logging for predictive maintenance, making them a popular choice for automating gate and globe valves.
Multi-turn Rotork actuators (such as the IQ range) rotate several turns to drive rising-stem valves like gate and globe valves, while quarter-turn Rotork actuators (such as the IQT electric range or RC200 pneumatic range) rotate 90° to operate ball, butterfly and plug valves. Choosing between multi-turn and quarter-turn depends on your valve type and required torque or thrust.
Yes — Rotork offers ATEX, IECEx and explosion-proof certified actuators for use in hazardous and potentially explosive atmospheres. Many Rotork electric and fluid power actuators are also SIL-rated to IEC 61508 for safety-related and ESD systems, and the Rotork Schischek range specifically covers explosion-proof HVAC actuator duty.
The Rotork CVA (Continuous Valve Actuator) is an electric modulating actuator built for precise, high-resolution control of linear and rotary control valves. Rotork CVA actuators deliver accurate positioning for continuous-duty control loops, offering an all-electric alternative to pneumatic control-valve actuators.
Rotork's fluid power range includes pneumatic and hydraulic quarter-turn and linear actuators such as the GT, GH and RC200 scotch-yoke ranges. These Rotork pneumatic actuators use compressed air (or hydraulic fluid) to automate quarter-turn valves, and are available in double-acting and spring-return fail-safe configurations.
Rotork Skilmatic actuators are self-contained electro-hydraulic actuators that combine the simplicity of electric operation with the reliability of hydraulic fail-safe action. The Skilmatic SI range gives spring-return fail-safe open or close on loss of power or signal, making it ideal for ESD and safety shutdown valve applications.
Yes — Rotork actuators support remote monitoring, control and asset management through systems such as Pakscan, Modbus, Profibus, Foundation Fieldbus and HART, plus Bluetooth setup and Rotork Intelligent Asset Management. This lets operators pull diagnostics and data logs from Rotork valve actuators to plan predictive maintenance and reduce downtime.
The Rotork CK range is a modular electric actuator platform offering flexible, cost-effective automation of multi-turn and quarter-turn valves, while the Rotork CMA range is a compact modulating actuator for control-valve duty. Both extend the Rotork electric actuator offering into smaller and mid-range valve applications.
Selecting the correct Rotork actuator depends on your valve type (multi-turn or quarter-turn), the required torque or thrust, the duty (on/off, modulating or fail-safe), the power source available (electric, pneumatic or hydraulic) and the area classification (safe or ATEX hazardous area). Share your valve details and we'll size and specify the right Rotork actuator for the job.
