This document applies to directly pneumatically operated pinch valves, sizes NPS ½ (DN 15) through NPS 24 (DN 600), of the shell and tube design, which have flanges that mate with ASME B16.1 Class 125 (PN20) and/or ASME B16.5 Class 150 (PN20) flanges. This document excludes solenoid-actuated valves, electric motor–operated valves, cylinder-operated valves, diaphragm-operated valves, pressure-reducing valves, and manually operated (handwheel) valves. This document applies only to pinch valves of the shell and tube design.

Purpose

The purpose of this document is to aid users in their piping design by providing installed face-to-face dimensions for pinch valves, of the shell and tube design, without giving special consideration to the manufacturer of the equipment to be used.
