Main technical content: This standard specifies the terms and definitions, structural types, basic requirements, technical requirements, test methods, inspection rules, marking, supply requirements, and quality commitments for steel check valves and lift-type check valves used in the petroleum, petrochemical, natural gas, and related industries. This standard applies to steel check valves, steel lift-type check valves (hereinafter collectively referred to as valves), with nominal pressures of PN16 to PN400 or Class 150 to Class 2500, nominal sizes of DN50 to DN400 or NPS2 to NPS24, and operating temperatures of -29°C to 538°C. The valve covers are bolted, and the end connections are flanges and welds. The valves have straight-through, angle, and Y-type structures with lifting stems, and are used in the petroleum, petrochemical, natural gas, and related industries. This standard also applies to steel check valves with pressure self-sealing valve covers.
