Festo
The Festo 8171469 is a 3/2-way closed, monostable industrial component featuring electrical actuation, a piloted type of control with internal pilot air supply, and a width of 18 mm. This plate seat valve delivers a normal nominal flow rate and standard nominal flow rate exhaust air of 125 l/min across an operating pressure range of 0.3 MPa to 1 MPa (3 bar to 10 bar). Equipped with a soft sealing principle, mechanical and pneumatic spring reset methods, non-detenting manual override, and IP65 protection, it supports any mounting position and a 100% duty cycle with holding current reduction. Additional functionalities include negative overlap, non-reversible flow direction, switching position sensing via a pressure switch for exhausted status, and signal status displays comprising a yellow LED for valve actuation and a green LED for pressure switch exhausted status.
