GSO EN 1984:2009 Scope
This European standard specifies the requirements for steel gate valves which are wrought, cast or fabricated with
end connections flanged, butt welding, socket welding or threaded.
This standard is applicable to steel gate valves mainly used for industrial and general purpose applications.
However they can be used for other applications provided the requirements of the relevant performance standards
are met.
The ranges of nominal sizes covered is:
DN8; DN10; DN12; DN15; DN20; DN25; DN32; DN40; DN50; DN65; DN80; DN100; DN125; DN150;
DN200; DN250; DN300; DN350; DN400; DN450; DN500; DN600; DN700; DN750; DN800; DN900; DN1000
DN750 is used for Class designated valves only.
DN8 and DN12 are not used for flanged end connections.
Socket welding end valves and threaded end valves are limited to the range DN8 to DN65.
The range of pressure designations covered is:
a) for flanged valves
PN10; PN16; PN25; PN40; PN63; PN100
Class 150; Class 300; Class 600
b) for butt welding end valves
PN10, PN16, PN25, PN40, PN63, PN100
Class 150, Class 300, Class 600
c) for socket welding end valves and threaded end valves
PN10; PN16; PN25; PN40; PN63; PN100
Class 600; Class 800
The progress of work of the various standards referred to in the normative references can require revision of this
standard
NOTE 1 Socket welding end and threaded end valves are not normally manufactured with the pressure designations PN10,
PN16, PN25 and PN40.
NOTE 2 Class 800 is an intermediate class designation widely used for socket welding and threaded end valves.
