Description
Flange Steel Ball Valve is used to control the flow of liquid or gas, and can be manually or automatically operated. The fluid resistance of this product is small, and its resistance coefficient is equal to that of pipe sections of the same length. The utility model has the advantages of simple structure, small volume and light weight. Its sealing surface has good sealing performance and has been widely used in vacuum systems. The ball valve is simple in structure, and the sealing ring is generally movable, so it is convenient to disassemble and replace. The sealing surfaces of the ball and valve seat are isolated from the medium, so when the medium passes through, it will not cause erosion of the valve sealing surface.
