Stainless steel ball valves can be closed with only a 90-degree rotation and a small torque. The completely equal body cavity provides the medium with little resistance, through the flow channel. Stainless steel ball valves are mainly characterized by their compact structure, and ease of operation and maintenance, stainless steel ball valves can be used to control the flow of air, water, steam, all kinds of corrosive media, mud, oil, liquid metal, and radioactive media and other types of fluids. Stainless steel ball valves can be monolithic or modular.
