three-piece ball principle

The three-piece ball valve only needs to be rotated 90 degrees and a small rotational torque to close tightly. The completely equal valve body cavity provides a straight flow path with little resistance for the medium. It is generally believed that the ball valve is most suitable for direct opening and closing. Development has designed the ball valve to have the function of throttling and controlling flow. The main feature of the ball valve is that it has a compact structure and is easy to operate and maintain. It is suitable for general working media such as water, solvents, acids and natural gas, and is also suitable for media with harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene. The ball valve body can be integral or combined. The three-piece ball valve is a relatively new type of ball valve. It has some unique advantages due to its own structure, such as no friction in the switch, the seal is not easy to wear, and the opening and closing torque is small. This allows the size of the actuator to be used reduced. Equipped with a multi-turn electric actuator, the medium can be adjusted and tightly cut off. It is widely used in petroleum, chemical industry, urban water supply and drainage and other working conditions that require strict cutting.
