The industrial automation and control is evolved from the plug valve, the ball valve opening and closing pieces as a sphere, the use of the ball around the axis of the valve rotation 90 degrees to achieve the purpose of opening and closing.
Ball valve in the pipeline is mainly used to cut, distribution and change the direction of media flow, designed to V-shaped opening of the ball valve also has a good flow regulation. The ball valve only need to rotate 90 degrees of operation and a small turning torque can be closed tight. The fully equal body cavity provides a very small, straight passage for the medium. Ball valve is not only simple structure, good sealing performance, but also in a certain range through the smaller size, light weight, less material consumption, installation size is small, and the driving torque is small, easy to operate, easy to achieve fast opening and closing, easy to operate And maintenance, suitable for water, solvents, acids and natural gas and other general working medium, but also for poor working conditions of the media, such as oxygen, hydrogen peroxide, methane and ethylene. single coil solenoid valve body can be the whole, it can be modular.
