About Pneumatic UPVC Butterfly Valve
"Pneumatic Plastic Butterfly Valve" means a regular Plastic Butterfly valve with a pneumatic actuator. Pneumatic valves are designed for quick opening and closing. A well-engineered combination of a powerful pneumatic actuator, fitted to our heavy duty high performance, ball valve. The Pneumatic actuator offers single acting (fail closed or open) or Double acting options. Double acting actuators use an air pressure signal (80-120 PSI) to open and close the valve. Single acting (Spring return) actuators use an air pressure signal (80-120 PSI) to open and springs to close the valve. The valve will fail closed upon loss of air signal. They rotate 90 degrees (quarter-turn) from fully open to fully closed. Sized on 5.5 bar pilot air supply with 30% added safety factor. This unit gives you an exceptional combination, that offers trouble free operation coupled with high performance. We offer this valve in Stainless Steel with various seat permutations and many accessories which can be fitted onto the actuator such as switch boxes, solenoids, positioners and filter pressure reducing valves.
Pneumatic actuated Plastic Butterfly valve is used for on-off control of water, air, and other media compatible with the materials of construction.
