See Chinese contents: GB 26640-2011 GB 26640-2011: [GB/T 26640-2011] Specification for minimal thickness of the shell of valves
This Standard specifies the wall thickness requirements for iron and steel valves such as ball valves, butterfly valves, gate valves, globe valves, check valves, plug valves and diaphragm valves. The parameter ranges of the valves to which this Standard applies are: a) Steel valves with nominal pressure PN 10~PN 760. Nominal pressure PN 760 is only suitable for welded end valves; b) Flange connection, wafer connection, and butt-welding connection end steel valves with nominal dimension not greater than DN 1250; c) Socket-welded end and threaded connection end steel valves with nominal dimension not greater than DN 100; d) Iron valves with nominal pressure PN 1.0~PN 25; e) Iron valves with nominal dimension not greater than DN 3000.
