Festo
The Festo 1002539 is an externally controlled industrial component featuring a poppet valve with a piston actuator and a soft sealing principle for pneumatic actuation. This monostable, 2/2-way closed valve supports in-line installation in any mounting position and handles gaseous media, vapor, inert gas, and filtered compressed air up to a 600 mm²/s viscosity within a medium temperature range of -10 °C to 80 °C. Operating pressures range from 0.6 MPa to 1 MPa (6 bar to 10 bar, or 87 psi to 145 psi) utilizing a 29 mm nominal width and a non-reversible flow direction above the valve seat.
