Pneumatic Angle Seat Piston Valves - Normally Open

Normally open pneumatic angle seat piston valves for applications requiring flow to remain open when control air is removed. Compressed air closes the valve, while a spring returns it to the open position. Stainless steel bodies and an angled seat provide a high-flow passage for compatible liquids, gases and steam. Choose from threaded and flanged connections, with selected models rated up to 16 bar and +200°C, depending on size and operating conditions. Check the required pilot air pressure, flow direction, seal compatibility and allowable differential pressure, or contact our technical team for selection advice.
