CEN/TC 69/WG 11 - Control valves

This European Standard applies to all industrial process control valves (hereafter referred to as control valves).
This European Standard specifies the design and performance requirements including material, pressure/temperature ratings, dimensions, testing and marking.
The range of nominal size is:
-   DN 10; 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 1 000; DN 1 200.
The range of PN is:
-   PN 10; PN 16; PN 25; PN 40; PN 63; PN 100; PN 160; PN 250; PN 320; PN 400.
The range of Class is:
-   Class 150; Class 300; Class 600; Class 900; Class 1 500; Class 2 500; Class 4 500.
Pinch valves are excluded from the scope of this European Standard.
Cast iron Class designated flanges are excluded from the scope of this European Standard.

This standard is applicable to all industrial process control valves (hereafter referred to as control valves). It establishes definitions and seat leakage classifications. It specifies the face-to-face dimensions and the requirements for inspection, testing and marking. This standard covers control valves from PN 10 to PN 100 and Class 150 to Class 600. The range of DN is according to the dimensions listed in the basic series from the EN 558-1 and EN 558-2.
