適用范圍：This European Standard specifies the requirements for steel gate valves which are wrought, cast or fabricatedwith end connections flanged, butt welding, socket welding or threaded.This European Standard is applicable to steel gate valves mainly used for industrial and general purposeapplications. However they can be used for other applications provided the requirements of the relevantperformance 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 valves1) PN 10; PN 16; PN 25; PN 40; PN 63; PN 1002) Class 150; Class 300; Class 600b) for butt welding end valves1) PN 10, PN 16, PN 25, PN 40, PN 63, PN 1002) Class 150, Class 300, Class 600c) for socket welding end valves and threaded end valves1) PN 10; PN 16; PN 25; PN 40; PN 63; PN 1002) Class 600; Class 800
