ABSTRACT:
A stop valve includes a housing formed with a continuous cylindrical bore; a pair of connecting sleeves are disposed one at each end of the housing and are coupled to it by means of coupling nuts. A spherical stopcock coupled to a shaft is positioned in the bore in the housing along with two sealing rings each adjacent to an opposite side of the stopcock, and two insert rings each arranged to push a different one of the sealing rings into contact with the stopcock. The insert rings are insertable into and held within the housing bore by bayonet-like points. A certain amount of axial play is provided between the connecting sleeves and the housing which is adjustable via the coupling units.
