TORK Pneumatic Actuators are powerful, reliable and compact double rack pinion units for use with ball, butterfly and plug valves and any device requiring accurate fast or slow or proportional 90 ° turn motion. TORK Pneumatic Actuators are manufactured 7 different sizes both double acting and single acting spring return type. Besides standard manufacturing program, optionally pneumatic actuators can be manufactured with ± %10 stroke adjustable, 180° turn and 3- position types (open, half open, closed). Any power operated device used to operate a valve. The device is designed to operate using motive energy which may be electrical, pneumatic, hydraulic, etc., or a combination of these. Movement is limited by travel, torque or thrust Pneumatic Actuator is an automatic control device which open and close the rotating valves with the help of compressed air. Pneumatic Actuators can be separated into two general groups: 1- Spring Return Actuators. 2-Double Acting Actuators. In Spring Return Actuators the opening operation is done by pressurized air and the closing is done by springs. In Double Acting Actuators opening and closing operations both are done by pressurized air. Pneumatic actuators are using in different piping systems to open or close the valves. This equipment also related to the fluids, flow in the pipes can be used in explosive regions(ZONE I). TORK Pneumatic Actuators are also SIL 3 certified.
