Electro-pneumatic 3/2-way pilot valve for use in seat design, has actuating tappet enclosed by conical shaped valve seats, where tappet passes into cylindrical area for guiding along lifting path

摘要

The valve has a ventilation connection (2) and an aeration connection (4) alternatively connected over coaxial valve seats (5a, 5b) by a sealing element (7) for ventilating and aerating an operating connection (3), where a sealing element is arranged between the seats. An electromagnetically movable actuating tappet (9) comes in attachment with a distal end at the sealing element by projecting through the seat (5a) of the aeration connection. The actuating tappet is enclosed by the conical shaped seats, where the tappet passes into a cylindrical area (6) for guiding along a lifting path.
