Check Valve

  • Butterfly Check Valve with Heavy Hammer

    Butterfly Check Valve with Heavy Hammer

    Butterfly check valve are widely used in water, waste water and sea water. According to the medium and temperature, we can choose different material. Such as CI, DI, WCB, SS304, SS316, 2205, 2507, Bronze, Aluminium. The micro-resistance slow-closing check valve not only prevents the back flow of media, but also effectively limits destructive water hammer and ensures the safety of pipeline use.

  • Axial Flow Silent Check Valve One Way Flow Non Return Valve

    Axial Flow Silent Check Valve One Way Flow Non Return Valve

    Silent Check Valve is a Axial Flow type check valve, the fluid behaves primarily as laminar flow at its surface, with little or no turbulence. The inner cavity of the valve body is a Venturi structure. When the fluid flows through the valve channel, it gradually shrinks and expands, minimizing the generation of eddy currents. The pressure loss is small, the flow pattern is stable, no cavitation, and low noise.

  • Silencing Check Valve Non Return Valve

    Silencing Check Valve Non Return Valve

    The silencing check valve is a lift check valve, which is used to prevent the reverse flow of the medium. It is also called a check valve, one-way valve, silencer check valve and reverse flow valve.

  • SS2205 Dual Plate Check Valve

    SS2205 Dual Plate Check Valve

    Dual plate check valve also called wafer type butterfly check valve. This kind of check vavle has good non-return performance, safety and reliability, small flow resistance coefficient. It is mainly used in petroleum,chemical, food, water supply and drainage, and energy systems. A wide range of materials are available, such as cast iron, ductile iron, stainless steel and so on.

  • DI CI SS304 Dual Plate Check Valve

    DI CI SS304 Dual Plate Check Valve

    Dual plate check valve also called wafer type butterfly check valve. This kind of check vavle has good non-return performance, safety and reliability, small flow resistance coefficient. It is mainly used in petroleum,chemical, food, water supply and drainage, and energy systems. A wide range of materials are available, such as cast iron, ductile iron, stainless steel and so on.

  • Ductile Cast Iron Rubber Flap Check Valve

    Ductile Cast Iron Rubber Flap Check Valve

    Rubber flap check valve is mainly composed of valve body, valve cover and rubber disc. W e can choose cast iron or ductile iron for valve body and bonnet. The valve disc we usually ues steel+rubber coating. This valve is mainly suitable for the water supply and drainage system and can be installed at the water outlet of the water pump to prevent back flow and water hammer damage to the pump.

  • Ductile Iron SS304 SS316 Non-return Swing Check Valve

    Ductile Iron SS304 SS316 Non-return Swing Check Valve

    Non-return swing check valve are used in pipes under pressure between 1.6-42.0. Working temperature between -46℃-570℃. They are widely used in industries include oil,chemistry, pharmaceutical and power generation to prevent the back flow of the medium. And the same the time, the valve material can be WCB,CF8,WC6, DI and etc.
