Rotork is the world’s leading designer and manufacturer of electric, pneumatic and hydraulic valve actuators, valve control systems, valve gearboxes and accessories. Rotork provides a single source for these products, supported by dedicated site services encompassing retrofitting, upgrading and life of plant maintenance, repair and support.
With over fifty years of global experience, Rotork has the expertise and product range to deliver virtually any actuation solution – from compact manually operated gearboxes to large highly specified actuators for use in extreme temperatures and hazardous environments. For every product, customers enjoy the support of over 150 Rotork offices and representatives located throughout Europe, North and South America, the Middle East, Asia, Africa, Australasia and the Far East.
Electric Valve Actuators: IQ Intelligent
Rotork’s flagship IQ intelligent electric actuator features legendary innovations including Rotork’s unique double sealing system and ‘non-intrusive’ infra-red commissioning, together with data logging and predictive maintenance capabilities by means of IQ-Insight software.
IQ functionality and reliability is available for industrial valves of virtually every size and description – multi-turn, quarter-turn, isolating and modulating. The IP68 watertight and temporarily submersible enclosure is available with ATEX certification for hazardous locations and approved for SIL (Safety Integrity Level) 2 and 3 applications. Control options include ‘bumpless’ Profibus connectivity, Foundation Fieldbus, Modbus, DeviceNet and Rotork Pakscan 2-wire dedicated actuator control systems.
Pneumatic and Hydraulic Valve Actuators
The Rotork Fluid Systems Division designs and manufactures pneumatic, hydraulic, gas-over-oil, high pressure gas and electro-hydraulic valve actuators. In the water and waste treatment industries these actuators are often used when, for example, failsafe or emergency shutdown (ESD) functions cannot be easily provided by electric actuators. Applications include pipelines, flood prevention equipment, fast acting operation (steam turbine protection) and pressure regulation.
In common with Rotork electric actuators, fluid power actuators are available with serial control networks including Profibus, Foundation Fieldbus and Rotork Pakscan to greatly reduce the installed cost and maintain control system compatibility throughout large or extended facilities.
Valve Gearboxes and Accessories
Rotork Gears manufactures multi-turn and quarter-turn gearboxes for either the manual operation of valves and penstocks or for use as secondary gearboxes with electric and fluid power actuators.
In addition the Division manufactures and supplies a full range of valve accessories encompassing mounting kits, switchboxes, positioners, solenoids, spools, pedestals, extension spindles, chainwheels and handwheels, completing Rotork’s offering as a “one stop shop” for valve actuation and control equipment for contracts of all sizes and complexity.
Rotork Site Services
Rotork Site Services Division offers expertise for the design, installation and commissioning of retrofitted actuators and control systems for plant upgrades and extensions, as well as site surveys, actuator audits, maintenance, repair and advice on valve actuation equipment from any manufacturer.
Site Services extend Rotork’s customer commitment beyond the initial supply of new equipment to cover the entire life of the plant, removing this responsibility from the plant owners and enabling them to concentrate on their mainstream businesses. The success of this policy is witnessed by Rotork’s selection as the preferred framework partner for valve actuation in the UK water industry and in similar partnerships throughout the world.
