Festo
3540143
Angle seat valve VZXF-L-M22C-M-A-N2-450-M1-V4B2T-50-4
Engineered with a poppet valve and piston actuator design, this Festo 3540143 industrial component provides a 2/2-way closed, monostable valve function with soft sealing and mechanical spring reset. The externally controlled unit operates within a medium pressure range of 0 bar to 4 bar and an operating pressure of 6 bar to 10 bar, accommodating vapor, inert gas, and filtered compressed air up to a maximum viscosity of 600 mm²/s across medium temperatures from -40 °C to 200 °C. Featuring in-line installation with any mounting position, the assembly includes a 45 mm nominal width, 2 NPT threaded sleeve cable connection, and internal G1/8 pneumatic connection.

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
