Pneumatic & Hydraulic Actuators

CP Range

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.

• Pneumatic actuators in double-acting and spring-return configurations
• Corrosion resistant cylinders
• Complies with EN60529 (1991) + (A1:2000) for IP67M
• Actuators certified to IP 66M/67M
• Actuators certified to ATEX 2014/34/EU
• Actuators certified in accordance with PED 2014/68/EU
• Torque output to 4,500 Nm
• Certified suitable for use at SIL3 as a single device in accordance with IEC 61508

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.
