Festo
The Festo part number 3535643 is an externally controlled industrial component featuring a poppet valve with a piston actuator, a soft sealing principle, and a 16 mm nominal width configured for 2/2-way, closed, monostable operation. Operating with a medium pressure range of 0 bar to 16 bar and an operating pressure of 6 bar to 10 bar, this non-reversible unit handles vapor, inert gas, and filtered compressed air up to 600 mm²/s viscosity across a medium temperature range of -40 °C to 200 °C. It utilizes in-line installation with a G3/4 threaded sleeve cable connection, a G1/8 internal thread pneumatic connection, and a mechanical spring reset method in any mounting position.
