Rotork is the world's leading manufacturer of electric, pneumatic and hydraulic valve actuators and associated control systems, valve gearboxes and valve accessories - supported by the Rotork worldwide service network.
The Rotork group of companies comprises three actuation divisions. In addition, Rotork Site Services provides worldwide planned and emergency actuation services, including actuator overhauling, health checks, retrofit, preventative maintenance and extended scope projects.
Electric valve actuators
Rotork Controls is Rotork's electric valve actuator division, offering an electrical solution to industrial valve control and actuation applications of virtually any size, description and complexity.
Rotork Controls' capabilities encompass actuators and control systems for new plants, plant extensions and upgrades, together with life of plant support. Rotork's unrivalled range of market-leading products offers a robust and economic solution for every valve duty and operating environment.
Fluid power valve actuators
Rotork Fluid Systems is dedicated to the design, manufacture, sale and support of high torque and reliable fluid power valve actuators on a global scale.
Manufacturing plants in Italy, Germany, the US and Sweden are supported by a strategic network of Centres of Excellence, serving application engineering, control system packaging, installation, commissioning and after-sales support for local industries.
Rotork Fluid Systems' commitment to quality and safety includes custom test systems to secure the correct operation and functionality of products and assist with research and development.
Valve gearboxes and accessories
Rotork Gears offers an unrivalled service for valve gearboxes and accessories, completing Rotork's status as the 'one-stop-shop' for valve actuation and control equipment for applications of all sizes and complexity.
Built in factories in the UK, US, Italy, Holland, India and China, gearbox products range from low-cost manual operators to highly specified versions for critical subsea or buried valve services.
In addition, Rotork Gears is the source for a complete range of positioners, switchboxes, solenoids, mounting kits, spools, pedestals, extension spindles, chainwheels and handwheels.
Actuators for the power generation industry
Rotork specialises in producing actuators and related equipment for every part of the power generation industry, including coal, oil and gas. As well as traditional power stations, Rotork products are used in renewable energy generation such as solar thermal plants and in CO2 emissions reduction processes such as flue gas desulphurisation, and carbon capture and storage.
We have over 50 years' experience in serving the power industry. We have a full range of actuators, all designed to meet the stringent requirements of the power generation industry and to provide the exacting levels of durability and reliability required.
Actuators help control everything that happens in a power plant. Rotork actuators are accurate, robust and efficient, backed by full service support. Rotork actuators provide precise control, lower costs, lower emissions and a safe environment. That's why power stations worldwide specify Rotork.
Our range of actuators is designed to fulfil all the requirements of the power generation industry.
The IQPro intelligent electric actuator range features legendary innovations, including Rotork's unique double-sealed enclosure, 'non-intrusive' infra-red commissioning, data-logging and predictive maintenance capabilities. IQPro functionality and reliability is available for valves of virtually every size and description, including multi-turn (rotary), quarter-turn, isolating and modulating, with watertight and hazardous area approvals to all internationally recognised standards.
The CVA and GPSA actuator ranges apply state-of-the-art electrical and mechanical technologies to the 'smart' operation of linear and rotary control valves demanding continuous, repeatable modulation, with a programmable fail to position option. The range demonstrates unrivalled control valve automation, combined with advanced, non-intrusive calibration and valve diagnostic technologies.
Electric actuator ranges also include the AWT for simplified control duties, ROM and Q direct-drive actuators for small quarter-turn valves and IEEE-qualified NA actuators for the nuclear power industry.
Control and serial communication options, encompassing Rotork's proprietary Pakscan and open systems including Profibus, Foundation Fieldbus, Modbus and DeviceNet, complete an unbroken chain of Rotork reliability from the valve to the control room and, via Ethernet, to anywhere on the planet.
Pneumatic, hydraulic, gas-over-oil, gas and electro-hydraulic actuators
Rotork Fluid Systems' product offering encompasses P, GP, CP, RC200 / RCI200 and R ranges of scotch-yoke and rack-and-pinion pneumatic actuators, H, GH and RH hydraulic actuators, the GO range of gas-over-oil actuators, the HPG range of high-pressure direct gas actuators and the Skilmatic range of electro-hydraulic actuators.
In addition to quarter-turn designs, most ranges are also available for linear valve applications. Many actuators are built for critical high-speed failsafe or emergency shutdown (ESD) duties in harsh locations, including subsea actuators for valves at depths measured in hundreds of metres.
