  • What Are the Features of Ball Valves

    The ball valve is not restricted by the installation direction, and the flow direction of the medium can be arbitrary. The fluid resistance is small, and the full-bore ball valve basically has no flow resistance.

  • How to Install The Pneumatic Butterfly Valve

    Before installation, check whether have all parts of the pneumatic butterfly valve, the model is correct, and there is no debris in the valve body, and there is no blockage in the solenoid valve and muffler.

  • What is the basic principle of ball valve?

    ​A ball valve operates on the principle of a hollow ball that rotates within a bore. The ball has a hole through it, which allows the flow of liquid or gas through the valve when the hole is aligned with the inlet and outlet ports of the valve.

  • Some Knowledge About Check Valve

    It relies on the pressure of flowing medium in the pipeline to push the valve disc to close and open the valve. When the medium stops flowing, the check valve disc will close. It can effectively prevent the medium in the pipeline from backflow.

  • Classification and selection of pneumatic plastic ball valves

    Pneumatic plastic ball valve is one of the types of anti-corrosion valves with the largest demand for various corrosive pipeline fluids. Compared with other valves, the biggest advantage is that the valve body is light in weight, has strong corrosion resistance, is easy to install and maintain, and is especially suitable for media Cleaner liquids and gases.
