  • Wafer Type Butterfly Control Valve

    Wafer Type Butterfly Control Valve

    Wafer type butterfly control valve are used for isolating and regulating flow. The closing mechanism is a disc that allows for quick shut off, much like a ball valve. Wafer type butterfly control valve are light in weight so they require less support. Unlike the ball valve, the disc is always present within the flow, therefore a pressure drop is always induced during flow, regardless of valve position. The disc is typically rotated a quarter turn when the valve is fully opened, but the valve may also be opened incrementally in order to throttle flow.
  • Brass Flange Gate Valve

    Brass Flange Gate Valve

    Brass Flange Gate Valve is the most common valve for water supply systems. It represents a linear-motion isolation valve and has a function to stop or allow the flow. Gate valves got their name from the closure element sliding into the flow stream to provide shutoff and, therefore, acting like a gate.
  • Offset Butterfly Valve

    Offset Butterfly Valve

    An Offset Butterfly Valve means that the stem does not pass through the centerline of the disc, but instead behind it (opposite of flow direction) . When the stem is located right behind the centerline of the disc, the valve is called single-offset. This design was developed to reduce the disc contact with the seal before full closure of the valve with the aim of improving service life of the valve.
  • Double Offset Butterfly Valve

    Double Offset Butterfly Valve

    Milestone Valve Co. Ltd. is a manufacturer specializing in the production of valves. It independently designs, develops, and produces various industrial valves such as butterfly valves, gate valves, ball valves, and check valves; the products are widely used in water conservancy, chemical, petroleum, agriculture, construction projects, etc. industry.

    Electric butterfly valve belongs to a variety of electric valve and electric control valve. The connection modes of electric butterfly valve mainly include:

  • 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.

  • How steam stop valve works

    It is not only suitable for medium and low pressure, but also for high pressure. For example, steam cast steel check values, especially bellows check values, are used in projects involving water, oil, steam, gas and other media. Since they are so widely used, this article analyzes its working principle in detail to help users understand and application.
