Stainless steel ball valve is a common type of valve, named after its working principle. The opening and closing element is a stainless steel ball that operates by rotating 90 degrees to open or close the valve. This valve is primarily used to shut off or connect the medium in the pipeline and is suitable for various media such as water, steam, gas, liquefied gas, and natural gas. Stainless steel ball valves offer advantages such as corrosion resistance, good sealing performance, low fluid resistance, and long service life, making them widely used in pipeline control applications.

Structure and Working Principle of Steel Ball Valves

The stainless steel ball valve mainly consists of a valve body, valve seat, sealing ring, valve stem, handwheel, etc. Its working principle involves the rotation of the valve stem, causing the stainless steel ball to rotate 90 degrees within the valve seat, thereby opening or closing the valve. The sealing ring of the stainless steel ball valve is made of special materials, providing excellent sealing performance. When the valve is closed, the sealing ring tightly fits against the valve seat, cutting off the flow of the medium. When the valve is open, the sealing ring separates from the valve seat, allowing the medium to flow smoothly.
