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 configurationsCorrosion resistant cylindersComplies with EN60529 (1991) + (A1:2000) for IP67MActuators certified to IP 66M/67MActuators certified to ATEX 2014/34/EUActuators certified in accordance with PED 2014/68/EUTorque output to 4,500 Nm (39,800 lbf.in)Certified suitable for use at SIL3 as a single device in accordance with IEC 61508
