Shut-off valve for fluids

摘要

The invention relates to a shut-off valve (10), comprising a valve housing (14), a valve piston (18) with a valve taper plug (22) arranged upstream of an associated valve seat (20), and a piston carrier (16) which holds the valve piston and can be displaced axially in the valve housing by means of a spindle (58). In order to avoid vibration of the valve piston (18), the valve taper plug (20) is guided axially by projecting webs (122, 124). <IMAGE>
