Abstract
A sealing arrangement for valve has at least one sealing ring, which has a substantially U-like cross section of its housing ring, which is made up of a plurality of parts which are permanently connected together. In the ring space of the housing ring a single, integral sealing element is mounted so as to be able to yield radially and with the housing ring it constitutes a component which may be uniformly handled. A sealing part thereof extends out of the housing opening of the ring space. A sealing ring of this type may be locked in valve housings in order to provide a sealing action between the valve housing and the moving valve piston. The design of the sealing rings makes them suitable for robotized assembly.
