Rotork RC200 scotch-yoke part-turn pneumatic actuator, double-acting and spring-return, IP67M, ATEX

Rotork RC200 is a range of compact pneumatic actuators for quarter-turn valves with a scotch-yoke mechanism. The torque profile provides high torque at the start and end of stroke, as required by ball valves and butterfly valves.

Double-acting and spring-return versions, optional integral handwheel. For comparable torque, the actuator has low weight and size and lower air consumption than rack-and-pinion actuators. IP67M protection, ATEX certification, ISO 5211 / DIN 3337 mounting. The range is stated as suitable for SIL 3 as a single device (IEC 61508) per size certificate.
