3-PC FULL PORT BALL VALVE

To have clean fluid like all other valves is also vitally important for ball valves. Therefore, filter should be certainly put before the valve, otherwise, filthy fluid will cause deformation on the surfaces of ball and gasket in a short time. In order to have a long life-cycle for these valves, valves should be turned on and turned off at least once in fifteen days. By taking their structures into consideration, they should be used just for the positions of fully turn-on and turn-off, not for decreasing or increasing. Sudden turn-on and turn-off should be avoided to eliminate the risk of water-hammer. As they consist of three parts, they have advantage of assembling and disassembling easily. They are suitable to use in the media of low pressure steam and gas, in the cold/hot/superheated water installations, the fluids that have no properties of acid and alkalli.
