Type K Damper Drives -
Rotork plc
The Type K Range offers rotary and linear pneumatic damper drives for utility power plants, refineries, powerhouse boilers, furnaces and process heaters that require precise combustion air and flue gas handling solutions. Type K damper drives have proven to increase boiler efficiency, reduce maintenance, lower fuel consumption and reduce harmful emissions.

GP/GH -
Rotork plc
GP (pneumatic) and GH (hydraulic) range scotch yoke actuators are designed to provide a rotary, quarter-turn movement for either on/off or modulating duty. The rugged yet compact design is available with two different yoke designs. The classic symmetric yoke delivers peak torque at both ends of stroke. Alternatively, they can be supplied with canted torque arms designed to deliver peak torque at only one end of stroke. Use of canted arms can often reduce actuator size, weight and cost for valves with appropriate torque demand characteristics.

RH -
Rotork plc
Rack and pinion actuators often offer the most economical solution for quarter-turn valves that have a fairly constant torque requirement throughout the stroke.
-
Remote Control Range -
Rotork plc
The Remote Control range is a family of valve actuators and associated products of the former Remote Controls AB of Sweden. These outstanding products are now backed by the vast global sales and service network of Rotork. Details of the product range are available from the links below and the menu on the left.

ACS -
Rotork plc
As specialist manufacturers of electro-hydraulic actuation and control equipment we offer comprehensive, purpose designed, engineered and manufactured solutions for the operation of choke and control valves for onshore and offshore installations. The electro-hydraulic stepping actuator provides a cost effective alternative solution to the mechanical ratchet style mechanism occasionally used for the positioning control of choke valves.
-
HPG -
Rotork plc
The HPG range of pipeline actuators are designed to use pipeline gas as the motive power source. They utilise our robust scotch yoke mechanism field proven the world over in all types of fluid power applications.
-
CP -
Rotork plc
CP range pneumatic actuators are a versatile, modular, scotch yoke design available in both double-acting and spring-return configurations. The compact and efficient design yields high torques even at low pressures. The design concepts found in Rotork's large, heavy-duty actuators has been applied to the CP range, which brings heavy-duty actuator qualities to small, quarter-turn actuators.
-
LP/LH -
Rotork plc
Rotork linear actuators offer the advantages of compact size, high performance and a simple but highly reliable design. They are ideal for operating on/off and control functions of both globe and wedge gate valves. Both spring-return and double-acting configurations are available with either pneumatic or hydraulic cylinders.
-
GO -
Rotork plc
The gas-over-oil range of pipeline actuators are designed to use pipeline gas as the motive power source. They utilise our robust GH and RH quarter-turn prime movers and are field proven in installations around the world. Control configurations are available to meet virtually any operational requirements.

HPU -
Rotork plc
Hydraulic power units (HPU’s) complement our extensive offering of rotary and linear actuators. We have over three decades of experience in their manufacture with units in service in a variety of plants and pipelines in locations spanning the globe. Although our HPU’s are primarily intended to power our hydraulic actuators they are of course suitable for other applications as well. And, in order to provide a complete range of options to best meet the requirements of any application, RFS also has the Skilmatic range of self-contained electro-hydraulic actuators.
