The invention relates to a stop valve, comprising a housing and a top and a closing component which is arranged in the housing in such a way that it can move and which has one or two sealing surfaces, each of which are brought to rest on a seat located in the housing or a seat ring located there, in a sealing position. The closing component has two side guide beads which interact with correspondingly shaped guide beads of the housing, in such a way as to produce a sliding guiding action over the entire path of displacement of the closing component and to support said closing component. According to the invention, the guide beads (8, 10) of the housing (1) are configured as separate parts which, in an area facing towards the housing (1) and/or the seat ring(s) (11), each have a contour that is received by a correspondingly shaped contour in the housing (1) and/or in the seat ring(s) (11) with a form fit. The guide beads (8, 10) also have an additional support in the form of the top (2). As a result, the guide beads can be worked more easily and better and can be aligned precisely. |
