where are the Check valves used？

       Check valve and its role is to ensure the directional flow in the pipeline without backflow function. The bottom valve pump suction pipe valve category also belong. Check valves are automaticvalves, pressure 1.6~25MPa/Class150-2500/2.0-42.0MPa working temperature is -29~+550 ℃, materials are: steel WCB, HT250,HT200. Cast iron, QT350, QT450, alloy steel WC6, WC9, CN7M stainless steel CF8 (M), CF3 (M). A105 forging steel, F304 (L),F316L piping. Various conditions of the petroleum, chemical,pharmaceutical, chemical, electric power industry and so on, it is used to water, oil, steam, acid medium. Is the control of the medium in the pipeline one-way flow valve, used to prevent the media back in the pipeline.

      Applicable occasions

      Butterfly double disc check valve is suitable for high-rise building water supply pipe network, a certain chemical corrosive mediapipeline, installation space limited network, also applies to the sewage pipe network.

Lift silent check valve suitable for network of water supply and drainage engineering high quality requirements; the pipe pressurerequirement is relatively high (PN2.5Mpa); can be installed in the pump outlet is economical and practical, water hammer check valve.

Engineering Chain

      Lifting type silencing check valve is used in water supply and drainage system of high-rise building, pipe network, can be installedin the pump outlet, slightly modifying the structure, can be used as the suction end of the valve, but not suitable for the sewage pipe network.

      Horizontal check valve suitable for diving, drainage, sewage pump,is particularly applicable to the sewage and sludge system.

     Swing type rubber check valve is suitable for living water supply network; but not for sediment sewage

      Swing check valve is suitable for the single water supply system,petroleum, chemical, metallurgical and other industrial sectors for the confined space installation is most applicable.
