Stainless steel flanged ball valves require only a 90 degree rotation and a small rotational moment to close tightly. Completely equal valve body cavity for the medium provides little resistance, straight through the flow channel. Ball VALVES ARE GENERALLY CONSIDERED BEST FOR DIRECT OPENING AND CLOSING, BUT RECENT DEVELOPMENTS HAVE DESIGNED THEM TO THROTTLE AND CONTROL FLOW. The main feature of ball valve is its compact structure, easy to operate and maintain, suitable for water, solvents, acids and natural gas and other general working media, but also suitable for poor working conditions of media, such as oxygen hydrogen peroxide, methane and ethylene. Ball valve body can be integral, can also be combined. This type of valve shall be installed in the horizontal direction of the pipeline.
Stainless steel flanged ball valves work by rotating the stem to open or block the valve. Ball valve switch light, small size, can be made into a large caliber, reliable sealing, simple structure, convenient maintenance, sealing surface and spherical surface is often in the closed state, not easy to be media erosion, is widely used in various industries
