Festo
The Festo 8122800 is a pneumatic industrial component featuring a rocker valve with a diaphragm seal and a soft sealing principle. This 3/2 monostable open/closed valve operates with a nominal width of 1.6 mm, a non-reversible flow direction, an adjustable exhaust air function, and a mechanical spring reset method. Designed for any mounting position using through-holes for M2 screws, it includes an external thread connection, a flange fluid connector, and an M3 pilot air port 21. Featuring piloted control with no manual override, the unit functions within an operating pressure range of -0.075 MPa to 0.1 MPa (-0.75 bar to 1 bar / -10.875 psi to 14.5 psi) and a pilot pressure range of 0.15 MPa to 0.3 MPa (1.5 bar to 3 bar / 21.75 psi to 43.5 psi).
