CP Range

CP range pneumatic actuators for quarter-turn valves 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 have been applied to the CP range, which brings heavy-duty actuator qualities to small, quarter-turn actuators.

GP / GH Range

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.

RC Range

RC200 range compact pneumatic actuators for quarter-turn valves feature a modern scotch-yoke mechanism that provides high start- and end-torque output in a very compact package. Available in both double-acting and spring-return configurations with an optional integral manual override. RC200 actuators have the lowest weight and the smallest external dimensions of any actuator with an equivalent torque output. This yields a compact and light yet robust valve/actuator package, particularly when a manual override solution is required. Another benefit is that they have less stroke volume than comparable rack and pinion actuators, providing a significant saving in the use of compressed air.
