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 1000; DN 1200. 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 1500, Class 2500, Class 4500. Pinch valves are excluded from the scope of this European Standard.
