Bi-directional Metal Seated Plug Ball Valve-Gas valve series-燃气阀厂家-上海冠环阀门制造有限公司

Product description

Bi-directional metal seated plug ball valve is developed by combining the superior sealing performance of the ball valve and the advantageous structure of the butterfly valve. It has the superior two-way pressure bearing of the fixed ball valve, can be used in liquid pipelines containing fine particles, etc. , long life and other practical advantages. Its essence is the combination of the structure and function of the butterfly valve and the eccentric half-ball valve, and the installation is superior to the half-ball valve and the fixed ball valve. The sealing principle combines the front end sealing of the fixed ball valve and the forced sealing of the eccentric butterfly valve, thereby realizing the high and low bidirectional cutoff in the pipeline. When the water pump stops running and the outlet water pressure of the pipeline is higher than the inlet water pressure, the use of the ball valve can effectively prevent the backflow of the return water, which is also the function that the butterfly valve and the half ball valve do not have.
