Three-piece ball valve is a new type of valve widely used in recent years. The working principle of the ball valve is to rotate the valve love to make the valve open or closed. Internal thread ball valve switch light, small size, can be made into a large calibre, reliable sealing, simple structure, easy maintenance, sealing surface and the ball surface is often in the closed state, is not easy to be eroded by the medium, in various industries have been widely used.
Three-piece internal threaded ball valves can be closed tightly with only a 90-degree rotation operation and a very small turning torque. The completely equal valve body cavities provide a low resistance, straight flow path for the media. Usually considered to be the most suitable for direct use of the ball valve, but recent developments have been designed to make the ball valve has throttling and flow control purposes. The main feature of the ball valve is its own compact structure, easy to operate and maintain, suitable for water, solvents, acids and natural gas and other general working media, but also for harsh working conditions of the media, such as oxygen, hydrogen peroxide, methane and ethylene. The ball valve body can be integral or combined.
Three-piece internal threaded ball valve is a relatively new type of ball valve category, it has its own structure unique to some of the advantages, such as friction-free switching, sealing is not easy to wear, opening and closing torque is small. This can reduce the specifications of the matching actuator. Equipped with multi-turn electric actuator, it can realise the adjustment and tight cut-off of the medium. Widely used in petroleum, chemical industry, urban water supply and drainage and other requirements of strict cut-off conditions.
