A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball to control flow through it. With compact structure and superb sealing effect, ball valves are durable, performing well after many cycles, and reliable, closing securely even after long periods of disuse. These qualities make them an excellent choice for shutoff and control applications. Ball valves' ease of operation, repair, and versatility lend them to extensive industrial use in chemical and steel industries, petroleum refining, electric power, long-distance pipeline transport, paper making, pharmaceutical, water conservancy, municipal projects, etc. As for pipeline transport, they can be selected for transporting oil, urea, water, steam, oxidant, natural gas, nitric acid and acetic acid, depending on different materials used.
