Class 1500 Ball Valve
Class 1500 Ball Valves are made of forged steel, to undergo the high pressure service. Class 1500 Ball Valves are available in floating and trunnion mounted ball valve; flanged, socket weld ends, bw ends and thread end.
Key Specifications / Features
Class 1500 ball valves are high pressure ball valves, it is PN260, 26 MPA. Forged steel is recommanded as valve body, and PEEK or better should be used as seat material.
For Class 1500 ball valves, trunnion mounted ball valves, ball valves should be adopted for 2″ and bigger; while the the biggest size for Class 1500 floating ball valve should no more than 1-1/2″.
Relia trunnion ball valve with cavity relief pressure when added to the valve pressure rating shall not exceed 133 % of the pressure rating of the valve at its maximum specified design temperature.
