Flanged End Pressure Seal Check Valve
KOSEN Flanged End Pressure Seal 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 Flanged End Pressure Seal 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 .

Forged Swing Check Valve
KOSEN Forged Swing Check Valves, also known as one-way valve, non-return valve and so on, is an automatic valve opening and closing itself by the force of flowing medium. And Forged check valve is mainly used for preventing the backflow of medium, the reversal of pump & its motor and the discharging of container. By different structure, it could be divided into forged swing type check valve & forged lift type check valve; If by different connection, it could be flanged forged check valve, socket welded forged check valve and etc.
