Cast steel Check Valve

GAIRUI Cast steel Swing 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 . GAIRUI Cast steel Swing 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 .

Overview

Check valve refers to a valve whose opening and closing parts are circular discs and rely on its own weight and medium pressure to generate actions to block the back flow of the medium. The disc of the swing check valve is disc-shaped, and it rotates around the shaft of the valve seat passage. It can prevent the medium from flowing backwards and weaken the hydraulic shock.
