◆ 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.

Design Feature+

◆ The fluid resistance is small, and its resistance coefficient is equal to that of a pipe section of the same length.

◆ Simple structure, small size and light weight.

◆ It is tight and reliable. At present, the sealing surface material of the ball valve is widely used in plastics with good sealing performance, and it has also been widely used in the vacuum system.

◆ Convenient operation, rapid opening and closing, only need to rotate 90° from fully open to fully closed, which is convenient for remote control.

◆ Convenient maintenance, simple structure of the ball valve, the sealing ring is generally movable, it is convenient to disassemble and replace.

◆ When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface when the medium passes.

◆ It has a wide range of applications, with a diameter ranging from a few millimeters to a few meters, from high vacuum to high pressure. When the ball rotates 90 degrees, it should show a spherical surface at the entrance and exit, so as to cut off the flow.
