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 European 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:
DN 8; DN 10; DN 12; DN 15; DN 20; DN 25; DN 32; DN 40; DN 50; DN 65; DN 80; DN 100; DN 125; DN 150; DN 200; DN 250; DN 300; DN 350; DN 400; DN 450; DN 500; DN 600; DN 700; DN 750; DN 800; DN 900; DN 1000.
DN 750 is used for Class designated valves only.
DN 8 and DN 12 are not used for flanged end connections.
Socket welding end valves and threaded end valves are limited to the range DN 8 to DN 65.
The range of pressure designations covered is:
a) for flanged valves
- PN 10; PN 16; PN 25; PN 40; PN 63; PN 100
- Class 150; Class 300; Class 600
b) for butt welding end valves
- PN 10, PN 16, PN 25, PN 40, PN 63, PN 100
- Class 150, Class 300, Class 600
c) for socket welding end valves and threaded end valves
- PN 10; PN 16; PN 25; PN 40; PN 63; PN 100
- Class 600; Class 800
NOTE 1 Socket welding end and threaded end valves are not normally manufactured with the pressure designations PN 10, PN 16, PN 25 and PN 40.
NOTE 2 Class 800 is an intermediate class designation widely used for socket welding and threaded end valves.
