ABSTRACT:
A wedge-shaped gate valve element (12) is held by a portable apparatus (10) in proximity to a tool (14) for refinishing sloped surfaces (16) of the element (12). The element (12) is gripped by a vise (92) which, in turn, is rigidly mounted to a vise support (86). The vise support (86) is mounted on a frame (17) of the apparatus. A support surface (90) of the vise support (86) is suitably inclined to give an upper sloped surface (16a) of element (12) a desired orientation with respect to the refinishing tool (14) which is also held in position on the apparatus (10).
