GO Range Actuator
The GO 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.
GH Range Actuator
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.
HPG Range Actuator
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. The actuator body is of rugged, ductile cast iron available in four body sizes. Cylinders are manufactured from carbon steel, electroless nickel-plated.
LH Range Actuator
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.
RH (hydraulic) actuators are available in five body sizes to produce torque output up to 3,400 Nm (30,000 lbf-in) at operating pressures up to 250 bar (3,600 psi). They are available in either double-acting or spring-return configurations.
RHQ actuators are designed for some of the most challenging valve actuation applications on earth. They are an excellent choice for the demanding requirements and adverse conditions found in applications for mining and offshore. The balanced design has a very compact footprint for a given output. Integral lifting lugs are designed to support the weight of both the actuator and the valve.
