Soft sealing ball valve
Not only has a simple structure and good sealing performance, but it is 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 easy to operate and can easily open and close quickly. It is one of the fastest growing valve varieties in the past decade. The soft sealing ball valve is evolved from the plug valve. Its opening and closing part acts as a ball and uses the ball to rotate around the axis of the valve stem to achieve the purpose of opening and closing. Soft-sealed ball valves are mainly used in pipelines to cut off, distribute and change the flow direction of media. They are used in chemical products, medicine and food operations. They are used in power operating systems of hydropower, thermal power and nuclear power. They are used in water supply and drainage, heating, and water supply in cities and industrial enterprises. The gas supply system is widely used in farmland drainage and irrigation systems and in financial management systems. It is an important mechanical product closely related to management and construction, national defense construction and people's lives. Manual soft-sealed ball valves are used in various pipeline systems to cut off or connect the flow of media so that the media can be transported to various designated points according to predetermined procedures. Product Features of Soft Seal Ball Valve
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.
Tight and reliable. At present, plastic is widely used as the sealing surface material of ball valves. It has good sealing performance and has been widely used in vacuum systems.
Easy to operate, it can open and close quickly from fully open to fully closed by simply rotating it for easy remote control.
Easy to maintain. The ball valve has a simple structure and the sealing rings are generally movable and can be easily disassembled and replaced.
When fully open or fully closed, the sealing surface of the ball and valve seat is isolated from the medium and will not cause erosion of the valve sealing surface when the medium passes through.
Wide range of application. The diameter ranges from a few millimeters to a few meters. It can be applied from high vacuum to high pressure. When the ball rotates, the inlet and outlet should all present spherical surfaces to cut off the flow.
