Festo
The Festo 1002509 is an externally controlled industrial component featuring a poppet valve design with a piston actuator and a soft sealing principle. It offers a 35 mm nominal width in a 2/2-way, closed, monostable valve function supporting non-reversible flow under the valve seat for gaseous and liquid media such as water, vapor, neutral liquids, mineral oil, and inert gas. Operating within a medium pressure range of 0 bar to 6 bar and an operating pressure of 6 bar to 10 bar, this unit utilizes G1 1/2 threaded sleeve connections according to DIN ISO 228 and permits installation in any mounting position.
