Commonly Used Stainless Steel Ball Valve - Threaded Ball Valve Features

Commonly used Threaded Ball Valve include wafer-type and flange-type valves. Wafer-type ball valves (stainless steel wafer-type ball valves) are connected between two pipe flanges using stud bolts. Flanged-type ball valves have flanges attached to the valve, with both flanges bolted to the pipe flanges. If a stainless steel ball valve is required for flow control, the key is to select the correct valve size and type. The structural principle of ball valves is particularly suitable for large-diameter valves. Stainless steel ball valves are widely used not only in general industries such as petroleum, gas, chemicals, and water treatment, but also in cooling water systems in thermal power plants.

The stainless steel wafer-type ball valve is a national key new product. This high-performance manual ball valve utilizes a double eccentric and a special tapered elliptical sealing structure. This overcomes the drawback of traditional butterfly valves, where the sealing surfaces remain in sliding contact and friction during the 0° to 10° opening and closing phases. This valve achieves a seal when the valve disc separates from the sealing surfaces upon opening and closes, extending service life and optimizing sealing performance.
