ANSI/ISA-75.10.02:2014

ANSI/ISA-75.10.02-2014 (R2024), Installed Face-to-Face Dimensions for Dual Pinch Flanged Clamp or Pinch Valves (Classes 125 and 150), provides standardized installed face-to-face dimensions for dual pinch flanged clamp or pinch valves classes ranging from nominal pipe standard (NPS) ½ to NPS 26. This standard is designed to aid users in piping design by providing precise dimensional data for handwheel-operated valves with flanges that comply with ANSI B16.1 Class 125 and ANSI B16.5 Class 150 standards, excluding solenoid or direct fluid-actuated valves. This standard includes tables detailing valve lengths in both inches and millimeters with tolerances, definitions of valve types and terminology and references to related standards from the American Society of Mechanical Engineers (ASME) and ISA. It highlights the variability in pinch valve applications and recommends consulting manufacturers regarding specific requirements and elastomer materials.
