Festo
3539037
Angle seat valve VZXF-L-M22C-M-B-G12-120-H3B1-50-16-EX4
The Festo 3539037 is a 2/2 closed, monostable industrial component featuring a poppet valve design with a piston actuator and soft sealing principle for line installation via a G½ threaded collar to DIN ISO 228. Operating with a 12 mm nominal size and external pneumatic piloting requiring 6 to 10 bar working pressure, it handles medium pressures from 0 to 16 bar across vapour, water, neutral fluids, inert gases, mineral oils, hydraulic oils, and filtered compressed air up to 600 mm²/s viscosity and -10 to 80 °C temperatures. Featuring a mechanical spring reset, non-throttleable exhaust-air function, and a G1/8 female thread pneumatic connection, this valve accommodates any assembly position for flow directions below the valve seat.
