Check Valve

  • Axial flow check valve

    Axial flow check valve

    Axial flow check valve as know as one-way check valve, the disc is open or close by means of medium flow and force, to prevent backflow of medium.
    Check valves are automatically used one-way flow of media channel, the media only allows flow in one direction in order to prevent accident.

  • DIN3202 -F1 lift check valve

    DIN3202 -F1 lift check valve

    DIN Lift check valve is an automatic sealing valve. The valve automatically open and close the disc by the flow of the medium itself, which effectively prevent the medium reverse flow.
    The disc with stainless steel spring can keep the valve work in any direction.
    The sealing surface is wear-resistant, corrosion-resistant and anti-friction, with long service life.
    The products is of resonable structure, reliable sealing, excellent performance and beautiful shape.

  • Wafer butterfly type check valve

    Wafer butterfly type check valve

    The wafer butterfly tpye check valve is small in volume and light in weight, and can be used as a device to cut off and adjust the flow in various medium pipelines. By selecting different materials for valve plate and seal seat, as well as through plate and shaft without pin connection, it can be used in more demanding working conditions, such as desulfurization, vacuum and desalination systems.

  • Rubber check valve

    Rubber check valve

    The opening and closing parts of rubber check valve can be opened or closed automatically by medium flow and force to prevent medium backflow. It is mainly suitable for horizontal water supply and drainage system and can be installed at the water outlet of water pump to prevent damage to the pump by backflow and water hammer. The valve disc is made of rubber and steel plate by high temperature pressing. It has the advantages of erosion resistance, good sealing performance, simple product structure, convenient maintenance, repair and transportation.

  • Wafer lift check valve

    Wafer lift check valve

    The main function of wafer lift check valve is that the water hammer pressure is very small, the valve disc stroke is short, the valve disc is light, it has the spring auxiliary closing and the valve closing speed is very fast. The structure length is very short, the volume is very small, the weight is very light, it brings great convenience for the valve installation, handling, storage and pipeline layout, and can save a lot of materials and reduce the cost.
