Committee will create standards on face-to-face dimensions for the various types of control valves as defined in ANSI/ISA-75.05.01-2000 (R2005), Control Valve Terminology, with the exception of clamp and pinch valves covered in ANSI/ISA-75.10.02-2008, Formerly ANSI/ISA-75.08-1999, Installed Face-to-Face Dimensions for Dual Pinch Flanged Clamp or Pinch Valves (Classes 125 and 150).


This subcommittee has been formed as successor to the ISA4 committee to prepare control valve face-to-face dimensional standards, and provide interchangeability between control valves made by various manufacturers.
