Pneumatic Angle Seat Piston Valves - Normally Closed

Normally closed pneumatic angle seat piston valves for controlling compatible liquids, gases and steam in industrial process systems. Compressed air opens the valve, while a spring closes it when control air is removed. Stainless steel construction and an angled seat provide a high-flow passage, with threaded and flanged connections available across the range. Selected models offer working pressures up to 16 bar and media temperatures up to +200°C, subject to size and operating conditions. Check the required pilot air pressure, flow direction and allowable differential pressure, or contact our technical team for selection advice.
