Ball Valve

The opening and closing component of a cast steel ball valve (the ball) is driven by the valve stem and rotates around the axis of the valve stem. It is primarily used to shut off or connect the medium within the pipeline and can also be utilized to regulate and control fluid flow. The hard-sealed V-shaped ball exhibits strong shearing force between its V-shaped ball core and the hard-faced alloy metal valve seat, making it particularly suitable for media containing fibers and small solid particles. Cast steel ball valves are generally categorized into manual cast steel ball valves, pneumatic cast steel ball valves, electric cast steel ball valves, cast iron ball valves, stainless steel ball valves, and copper ball valves. This valve is suitable for pipelines in systems such as petroleum, chemical, food, pharmaceutical, paper-making, hydroelectric power, marine, water supply and drainage, smelting, and energy. It can serve as a regulating and shut-off device for various corrosive and non-corrosive gases, liquids, semi-fluids, and solid powder pipelines and containers.
Product Parameters:
The valve is primarily used to shut off, distribute, and change the flow direction of the medium within the pipeline. Ball valves are a new type of valve that has been widely applied in recent years. They have the following advantages:
Low fluid resistance, with a resistance coefficient equal to that of a pipe segment of the same length.
Simple structure, small size, and lightweight.
Tight and reliable. The sealing surface material of ball valves is widely used in plastics, providing good sealing performance, and they are also widely used in vacuum systems.
Easy to operate, quick to open and close, requiring only a 90-degree rotation from fully open to fully closed, making it convenient for remote control.
Easy maintenance. Ball valves have a simple structure, and the sealing ring is generally movable, making disassembly and replacement convenient.
When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, preventing erosion of the valve's sealing surfaces when the medium passes through.
Wide application range, with diameters ranging from a few millimeters to several meters, and applicable from high vacuum to high pressure.
Ball valves have been widely used in sectors such as petroleum, chemical, power generation, paper-making, nuclear energy, aviation, and rocket science, as well as in people's daily lives.
