Seat Switching Valves

With its low flow resistance and compact design, the Pierburg poppet valve offers the ideal solution for a wide range of vehicle applications. Thanks to the modular design, connectors as well as hydraulic and mechanical connections can be designed individually according to customer requirements.

Furthermore, with the option for direct motor mounting, the Pierburg poppet valve can be used as a cost-efficient block valve for split cooling applications. The smallest leaks can be realized by means of the optionally available pressure equalization. Moreover, our valves offer best-in-class durability with more than 8 million operations.

Thanks to the plastic overmolded magnetic coil, we offer the best possible corrosion protection.
