Scope

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.

Summary	This Chinese standard specifies the ball valve, butterfly valve, gate valve, globe valve, non-return read, plug and diaphragm valves such as iron and steel wall thickness requirements. This standard applies to the range of the valve parameters: a) Nominal pressure PN 10 ~ PN 760 steel valve, nominal pressure PN 760 only applies to welding end valves, b) nominal size not larger than DN 1250 flange connection, wafer connections and welded steel valves connecting terminal, c) is not greater than the nominal size DN 100 for socket weld end and threaded end steel valves, d) nominal pressure PN 1. 0 ~ PN 25 made ??of iron valves, e) nominal size is not iron valves larger than DN 3000 's.
