Festo
The Festo 1002551 is a 2/2-way, closed, monostable industrial component featuring a poppet valve structural design with a piston actuator and soft sealing principle. Operating via pneumatic actuation with an external control pressure of 0.6 MPa to 1 MPa (6 bar to 10 bar, 87 psi to 145 psi), it accommodates a medium pressure range of 0 MPa to 1.6 MPa (0 bar to 16 bar) and medium temperatures from -40 °C to 200 °C. Designed for in-line installation in any mounting position, this non-reversible unit handles vapor, inert gas, and filtered compressed air with a nominal width of 24 mm, a G1/8 internal thread pneumatic connection, and a 1 NPT threaded sleeve cable connection per ANSI/ASME B 1.20.1.
