Festo
3539181
Angle seat valve VZXF-L-M22C-M-B-G34-160-H3B1-50-16-EX4
The Festo 3539181 is a 2/2 closed, monostable industrial component featuring a poppet valve design with a piston actuator, pneumatic actuation, and a soft sealing principle. Designed for line installation with a G¾ threaded collar to DIN ISO 228 and a 16 mm nominal size, it operates with media pressures from 0 to 16 bar and handles vapour, mineral oils, inert gases, water, and filtered compressed air within a medium temperature range of -10 to 80 °C. This externally piloted valve relies on a mechanical spring reset, a G1/8 female threaded pneumatic connection, and a working pressure of 6 to 10 bar for media flows below the valve seat up to a maximum viscosity of 600 mm²/s.
