摘要

The valve has a seal seat (20) arranged in a longitudinal direction to a valve closing body (10). The body has a cylindrical guiding element (12) and a sealing element (14) i.e. ball, that is spherically oriented at the seal seat. The sealing element is provided in longitudinal direction to the guiding element. The sealing element is held by the guiding element. The guiding element has a hollow cylindrical inner chamber in which a return spring is arranged axially, where the guiding element and/or the sealing element are made from plastic.
