Application Summary AI generated
This standard specifies the structural dimensions, technical requirements, test methods, and inspection rules for flanged and wafer-type resilient-sealed butterfly valves. It is applied in industrial fluid systems, such as water supply, drainage, heating, and general pipeline applications, where the valve provides tight shut-off and flow regulation for clean or slightly contaminated media. The standard ensures interchangeability and performance consistency for valves used in moderate-pressure and temperature conditions.
