ABSTRACT:
A stop valve includes a main body which defines a fluid passage and a valve chamber. The stop valve further includes a spindle having one end connected to a handle and the other end inserted into said valve chamber, a valve seat positioned in said fluid passage and confronting said valve body, and a cap member positioned above said valve chamber. The outer end of the spindle is coupled rotatably to the valve body, while the rotation of the valve body is prevented by a rotation preventive means. A packing is interposed between the valve body and the valve chamber. The valve body is in sliding contact with said packing along the axial direction thereof during operation, upon rotation of the spindle about its axis.
