  • Stainless Steel Welded Ball Valve

    Stainless Steel Welded Ball Valve

    A Stainless Steel Welded Ball Valve is used to control the flow of gas or liquid through a passage. It is distinct from other ball valves because its ball is mounted and welded onto a trunnion at the base and supported by the stem at the top.
  • Plunger Globe Valve

    Plunger Globe Valve

    In plunger globe valves, valve clack and valve seat are designed by the plunger principle. The valve clack is polished into a plunger and connected to the valve stem. The sealing is achieved by two elastic seal ring that sheathed on the plunger. The two elastic seal ring are separated by a sleeve ring and the rings around the plunger are held tight by a load applied to the bonnet by the bonnet nut. Globe valves are mainly used for opening and closing flow.
  • Soft Sealing Gate Valve

    Soft Sealing Gate Valve

    The soft sealing gate valve is suitable for non-corrosive liquid and gas medium at room temperature (≤80℃), such as clean water, air, oil, water treatment, sewage and other pipelines. The soft-seal gate valve has a very good sealing effect, almost Achieve zero leakage.
  • 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.
  • 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.
  • Welded Ball Valve

    Welded Ball Valve

    Welded Ball Valve is packed with corrosion agent avoids stem rusted . Deep Stuffing box guarantees long packing usage life.Welded seating ring effectively eliminates pipe leakage.

  • Precautions for the Installation of Wafer Check Valves

    Wafer check valve refers to the automatic opening and closing of the valve flap by the flow of the medium itself, which is used to prevent the medium from flowing back and the pump and the motor are reversed. Check valves can also be used to supply pipelines for auxiliary systems where the pressure may rise above the system pressure.

    A ball valve is a valve with a spherical core, which is opened and closed by driving the ball to rotate 90 degrees through the valve stem.

  • Practical Application of Multifunctional Pump Control Valve

    Multifunctional pump control valve is a new type of hydraulic valve with automatic operation in the whole process. It can fully realize the slow opening when the centrifugal pump is started, and two-stage fast closing and slow closing when it is stopped, so as to prevent the backflow of medium in the pipeline.

  • Direction of Valve Installation

    Many valves are directional in installation, such as globe valve, throttle valve, pressure reducing valve, check valve, etc. if the position is reversed, the service effect and service life of the valve will be affected (such as throttle valve), or it will not work at all (such as pressure reducing valve), or even cause danger (such as check valve). General valve, there is direction mark on the valve body. If not, it should be correctly identified according to the working principle of the valve.
