Cast Steel Non-slam Nozzle Check Valve

The KOSEN Axial flow Check Valve is composed of valve body, valve seat, guide body, disc, bearing and spring. The internal flow path is streamlined design, the pressure loss is small, the valve opening and closing stroke is very short, the pump can be closed quickly when the pump is stopped, so as to prevent the sound of the huge water hammer and form the silent effect. The valve is mainly used in water supply, drainage, fire fighting, HVAC, petrochemical, electric and other industrial projects. It can be installed at the outlet of the pump to prevent the reverse flow of medium and the damage to the equipment by water hammer.

KOSEN Forged Pressure Seal Swing Check Valves is a valve which is automatically opened and closed by the flow of the medium itself. It is used to prevent the reverse flow of the medium. It is also called the reverse check valve, the one-way valve, the countercurrent valve and the back pressure valve. The check valve is an automatic valve. Its main function is to prevent the backflow of the medium, prevent the reversing of the pump and drive motor, and the discharge of the container medium. The check valve can also be used to supply pipelines where the pressure may exceed the system pressure. Disc check valve around the pin inside the valve seat. The disc check valve is simple in structure and can only be installed on horizontal pipes with good tightness.

KOSEN Butterfly Type Check Valves is a double offset , triple offset butterfly type check valve. It is equipped with a buffer to slow down the closing speed to make partial medium enter the system in order to greatly eliminate the backflow slamming and the destructive pressure surge when pump stops working. It is mainly mounted at outlet side of the pump station in industrial water recycling supply system, urban water supply system, high-rise buildings and modern hotels. The model is designed to have non-vibration non-slam performance in consideration of special application environment. It has good sealing, smooth operation, long service life, energy saving advantage to make the living environment quiet and comfortable.

The KOSEN Non-slam nozzle check valves is a streamlined venture port design so as to reduce pressure loss. This series valve disc is the only moving part to minimize internal wear and compressed disc spring initiates valve closure as flow slows down and provides quick reaction on flow velocity change. It can be used in a wide range of critical and demanding services applications such as fast reversing reciprocating compressor system or installations where the check valve must be placed in close proximity to the pump inlet or outlet.
