Pneumatically Actuated
Our Pneumatic Actuators feature a rack and pinion design for quick on/off operations. A solenoid or related device is required for operation. Air can be piloted by direct mount solenoid valves havingNAMUR interfaces or remotely piloted via means of 1/8” NPT female threaded ports in the actuator interface plate. Two pneumatic styles are offered: Double-acting, which uses air to move pistons in both directions and spring-return which uses air to move pistons in one direction and springs in the other. Double-acting is the most popular since it offers a compact size and longest service life at the lowest cost. Limit switches are available for all models to remotely denote valve position or to connect with other devices.
Advantages
A special rack and pinion design supports extended service life and precise machining assures 90°rotation without external adjustment. Actuator bodies manufactured from lightweight aluminum withTeflon® impregnated hard anodized surfaces and stainless steel hardware provides excellent corrosion resistance. Actuators are maintenance-free and permanently lubricated with no airline lubrication needed. Mounting system precisely couples the actuator drive shaft to the stem, and the valve stem nut is fixed within the actuator shaft. These products minimize backlash, ensure optimum stem seal life and prevent stem nut back off.
