? The floating soft-seal ball valve is not only simple in structure, good in sealing performance, but also small in size, light in weight, low in material consumption, small in installation size, and small in driving torque within a certain nominal passage range. It is simple to operate and easy to achieve quick start. Closed, is one of the fastest growing valve varieties in the past ten years. The PTFE soft-seal ball valve is evolved from the plug valve. Its opening and closing part is used as a sphere, which uses the sphere to rotate 90° around the axis of the valve stem to achieve the purpose of opening and closing. Floating ball valves are mainly used in pipelines to cut off, distribute and change the direction of medium flow, in the production of chemical products, medicine and food; in the power production system of hydropower, thermal power and nuclear power; in the water supply and drainage, and heating of urban and industrial enterprises , And gas supply system; in the irrigation and drainage system of farmland; widely used in metallurgical production system. It is an important mechanical product closely related to production and construction, national defense construction and people's lives. Floating soft-sealed ball valves are sealed in various pipeline systems to cut off or connect the medium flow, so that the medium can be transported to each designated point according to a predetermined procedure.
