Forged Pressure Seal Swing Check Valve

KOSEN DIN Lift Check Valves is used to prevent back flow in the line .Flow is in a straight line through the valve resulting in minimal pressure drop . The disc swings into the open position as the media flows through the line .Back pressure in the line holds the disc in the closed position .
KOSEN DIN Lift Check Valves may be installed in horizontal or vertical lines ,but must be installed in proper relation to the media flow as indicated by the flow direction arrow marked on the body .

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.

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.

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.
