Pneumatic valve actuator PA

90°rack-and-piniondouble-acting

•Prelubricated and tested to minimum 1 million operations •Direct valve mounting per ISO5211 •Visual valve position indicator •Extruded aluminium body with 50 micron hard anodizing •Corrosion resistance -500 hour minimum salt spray test •Spring return models use precompressed spring cartridges •Female double square output drive •Namur mounting pad for direct mount solenoid valves •Standard VDI/VDE 3845 mounting for top mount accessories Applications Flapcon air actuators are typically used to operate quarter turn ball valves, butterfly valves and plug valves. They can also be applied virtually anywhere a 90 degree rotation is required such as dampers. Quick and easy to install with standard ISO 5211/DIN 3337 mounting dimensions and a double square female output drive. The operating tempera turerange of the actuator is – 20 to 80°. Operation Double acting actuators require air pressure to open and air pressure to close. Spring return actuators require air pressure to open and utilize springs to close for fail safe operation. Typically 4-way pilot valves are used to control a double acting actuator and 3-way pilot valves for spring return models. Pilot air should be filtered, dry or lubricated. Output drive rotates counter clockwise to open when viewed from top of actuator.
