ANSI/ISA-75.10.02-2008, Installed Face-to-Face Dimensions for Dual Pinch Flanged Clamp or Pinch Valves (Classes 125 and 150), has been approved as an American National Standard and is expected for public release soon, according to ISA (www.isa.org). The standard applies to valves, sizes NPS ½ (DN 15) through NPS 26 (DN 650), of the clamp or pinch valve design incorporating clamp or pinch elements.
The standard is designed to aid users in 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.
