Festo
The Festo 3540796 is an externally controlled industrial component featuring a 2/2-way, closed, monostable valve function with a poppet valve and piston actuator design. Utilizing soft sealing, a mechanical spring reset, and a nominal width of 43 mm, this unit supports a non-reversible flow direction above the valve seat for vapor, inert gas, and filtered compressed air media up to 600 mm²/s viscosity. It operates within a medium pressure range of -0.09 MPa to 0 MPa and an operating pressure of 0.6 MPa to 1 MPa, incorporating G2 threaded sleeve cable connections and G1/8 internal thread pneumatic connections for any mounting position via in-line installation.
