Stainless steel ball valves are widely used in industries such as petroleum, chemical, natural gas, electricity, pharmaceuticals, and food. In the field of oil and natural gas, stainless steel ball valves are used to control fluid flow in oil and gas pipelines; In the chemical industry, stainless steel ball valves are used to control the transportation of various corrosive media; In the field of power, stainless steel ball valves are used to control the cooling water circulation of boilers and steam turbines; In the pharmaceutical and food industries, stainless steel ball valves are used to control clean and sterile fluid delivery.

Stainless steel ball valves mainly consist of valve bodies, spheres, valve stems, seals, and other parts. The valve body is made of stainless steel materials, such as 304, 316, etc., which have good corrosion resistance and high temperature resistance, and can operate stably for a long time in various harsh environments. As the control element of the valve, the sphere rotates 90 degrees to achieve the opening and closing of the valve. The sealing element is responsible for ensuring the sealing performance of the valve in the closed state, usually made of PTFE (polytetrafluoroethylene) or other high-performance materials.
