Pneumatic piston valves are a type of 2/2-way compressed air operated globe valve for liquids, gases, steam and some aggressive liquids (also vacuum services). The piston is different from its competitors with its innovative design and is long-lasting. With its seat design, it creates lossless flow conditions at high flow rates. The seal group is machined on precision CNC machines. The compression spring is made of stainless steel. A wide range of accessory items are available, including limit switches, solenoid valves, additional manual control, stroke limiters.
