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.
