Pneumatic On-Off Control Valves
Pneumatic Actuated Ball Valve
The pneumatic actuated ball valve is an automatic ball valve with ISO 5211 connection, rack-and-pinion pneumatic actuator, controlled by compressed air that opens and closes in a quarter turn. It is the fundamental valve for automation lines requiring fast, reliable and frequent on-off control.
Available with single acting (spring-loaded, fail-safe position when air is cut off) and double acting actuator options; in 2 and 3-piece threaded stainless, flanged stainless, carbon steel and brass body models from DN15 to DN200, in pressure classes PN16–PN63. Solenoid valves and limit switches can be installed on the NAMUR interface.
