This document applies to valves, sizes NPS 1/2 (DN 15) through NPS 26 (DN 650), of the clamp or pinch valve design incorporating clamp or pinch elements. The purpose of this document is to aid users in their piping design by providing installed face-to-face dimensions for control valves, incorporating clamp or pinch elements, which have flanges that mate with ANSI B16.1 Class 125 and/or ANSI B16.5 Class 150 flanges, without giving special consideration to the manufacturer of the equipment to be used.
