We help maximise use of resources, meet all standards for quality, and maintain full and effective control of every part of operations. We are the world’s largest independent manufacturer of heavy-duty valve actuators and our products control thousands of valves in water and sewage plants across the world.
Watertight electric actuators
The Rotork range of IQ actuators are completely watertight and are specially designed for the water and waste water industries, with a wide range of specifications to suit every application in every part of the plant.
The IQ range features legendary innovations including Rotork’s unique double-sealed enclosure, ‘non-intrusive’ infra-red commissioning, data-logging and predictive maintenance capabilities. IQ 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.
Rotork’s electric actuator ranges also includes the AWT range, which features the qualities of a robust three-phase electric motor and a well-proven mechanical drive of the utmost simplicity, combined with limit switching and a choice of indication options.
The Skilmatic range of actuators combines simple electric operation with the precision of self-contained hydraulic control and the reliability of spring-powered failsafe action.
Gearboxes for electric actuators
Rotork Gears gearboxes are designed to adapt IQ actuators (both multi-turn and quarter-turn) for the high torque requirements of very large valves and penstocks.
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.
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.
Customers also benefit from Rotork’s international sales and service organisation of 350 offices worldwide, providing even greater global coverage and ensuring a swift and effective response to customer requirements.
