Abstract: A valve, which has at least one seal ring arranged in a recess of a valve housing, which seal ring has a seal housing having a U-shaped cross-section, in which seal housing an annular sealing element is arranged. The seal housing has a multi-part design and contains at least one separate housing leg, which is fixed to an annular bottom section of the seal housing in a joining region. The sealing element has a static sealing section, which engages in a sealing groove formed in the bottom section and is suitable for interacting with the two groove flanks of the sealing groove in a sealing manner.

Abstract: A valve includes at least one seal ring arranged in a recess of a valve housing, which seal ring has a seal housing having a U-shaped cross-section, in which an annular sealing element is arranged. At least one of the two housing legs of the seal housing is designed as a guiding leg, which effects transverse support and linear displacement guidance of a valve slide that passes through the seal ring.

Abstract: A pilot controlled pulse valve has a valve spool releaseably held in both terminal positions by latching means. The latching means comprise a permanent magnet means holding the valve spool by magnetic force. To set the terminal or end position the permanent magnet means has an abutment means placed to the fore of it. In order to protect the permanent magnet means against damage the abutment means bears against the valve housing independently of the permanent magnet means.
