This European Standard specifies the requirements for cast iron globe valves in straight, angle or oblique pattern (see EN 736 2) with flanged or threaded end connections. This European Standard is applicable to cast iron globe 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 range of nominal sizes covered is:a)flanged: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.b)threaded:½, ¾, 1, 1¼, 1½, 2.The range of pressure designations covered is:a)for flanged end valves:PN 6; PN 10; PN 16; PN 25; PN 40;b)for threaded end valves:PN 6; PN 10; PN 16.
