RTK Pneumatic Spring Diaphragm Actuators

RTK pneumatic spring diaphragm actuators deliver reliable linear actuation for control and on/off valves using instrument air and internal spring return action. Designed in a compact, multi-spring diaphragm format, these actuators are easily field reversible between fail open and fail close and mount directly to RTK and other industry standard valve bodies. A range of diaphragm areas accommodates light to heavy thrust requirements, and standard pneumatic accessory interfaces support positioners, limit switches, pilots, and solenoids for automated valve control in industrial process systems.
