  • Centerline Butterfly Valve

    Centerline Butterfly Valve

    Flange Centerline butterfly valve is a gate valve that has different modifications. The gate is in the shape of a disc that is attached to a centered axis. The look resembles a butterfly. The centerline design allows for the control of the fluid flow.
  • Wafer Type Hard Seal Butterfly Valve

    Wafer Type Hard Seal Butterfly Valve

    The wave type hard seal butterfly valve produced by milestone Industrial Co. Ltd. adopts stainless steel sealing ring. The elastic sealing ring has three eccentric contact with the butterfly plate, which realizes the effect of separating the sealing surface at the moment of opening and sealing at the moment of closing, so as to prolong the service life and achieve the best sealing performance. Therefore, wave type hard seal butterfly valve is widely used in metallurgy, electric power, petroleum, chemical industry, air, gas, combustible gas, water supply and drainage and other corrosive medium pipelines with medium temperature ≤ 550 ℃. Wafer Type Hard Seal Butterfly Valve is the best device to regulate flow and cut off fluid.
  • Gas Trunnion Mounted Side Entry Industrial Ball Valve

    Gas Trunnion Mounted Side Entry Industrial Ball Valve

    Milestone is a professional leader China Gas Trunnion Mounted Side Entry Industrial Ball Valve manufacturer with high quality and reasonable price. Welcome to contact us.The Gas Trunnion Mounted Side Entry Industrial Ball Valve is a form of quarter-turn valve which uses a hollow, perforated and fixed ball to control flow through it.
  • 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.

  • Cast Iron Globe Valve

    Cast Iron Globe Valve

    Cast Iron globe valve is a forced-sealing valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface to not leak. When the medium enters the valve from below the disc, the resistance that the operating force needs to overcome is the friction force of the valve stem and packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve, so Cast Iron The diameter of the valve stem of the globe valve should be large, otherwise the valve stem will bend up failure.

  • The selection criteria for check valves

    The installation position of the swing check valve is not restricted. It can be installed on horizontal, vertical or inclined pipelines. If installed on a vertical pipeline, the medium flow direction must be from bottom to top

  • Why are Triple Eccentric Butterfly Valves More and More Widely Used

    Many industries require more and more valves. If double eccentric butterfly valve are required to withstand high temperature, hard seal must be used, but the leakage of hard seal butterfly valves is large; If the valve is required to leak zero, the valve must be soft sealed, but the soft seal butterfly valve is not resistant to high temperature.

  • Fixed ball valve performance advantages

    Fixed ball valve is a new generation of high-performance ball valve, suitable for long-distance pipelines and general industrial pipelines. Special considerations have been taken in its design such as strength, safety, and resistance to harsh environments.

  • What is a soft seal ball valve? Working principle of soft seal ball valve

    Soft seal ball valve is a commonly used control valve, which consists of a ball, valve body, valve stem, soft seal, handwheel, etc. The ball is fixed by the valve body and the valve stem. A handwheel is installed on the valve stem. The handwheel drives the ball to rotate through the valve stem, thereby controlling the opening and closing of the valve.
