Festo
The Festo 1002556 is a 2/2-way closed monostable industrial component featuring a poppet valve with a piston actuator, soft sealing principle, and mechanical spring reset. Designed for in-line installation in any mounting position, this externally controlled pneumatic valve handles a medium pressure range of 0 MPa to 1 MPa (0 bar to 10 bar) and operating pressures from 0.6 MPa to 1 MPa (87 psi to 145 psi) across gaseous and liquid media including vapor, water, neutral liquids, mineral oils, and inert gases up to a maximum viscosity of 600 mm²/s and a medium temperature range of -40 °C to 200 °C. It features a nominal width of 31 mm, a threaded sleeve 1 1/4 cable connection as per ANSI/ASME B 1.20.1, an internal thread G1/8 pneumatic connection, and a non-reversible flow direction under the valve seat with a fitting nominal pressure PN of 40.
