Forged Pressure Seal Swing Check Valve
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.

Forged Bronze Check Valve
KOSEN Forged Bronze 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 Forged Bronze 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 .
DIN Lift Check Valve

Ball Type Check Valve
The KOSEN Ball Type Check Valves is composed of valve body, valve plate and spring. It is suitable for the supply and drainage pipes. The valve is guided by the central axis of both ends of the import and export. The valve is flexible and can be installed horizontally or vertically. The valve disc is loaded by spring, and its quick closing can effectively reduce the water hammer pressure, seal performance is good, shut off without noise. It has the advantages of small volume, light weight, small fluid resistance, fatigue resistance and long life.
