H44X-10 Cast Iron Swing Check Valve Nodular Flange Rubber Flapper Check Valve

Swing Type One-Way Check Valve With Nodular Cast Iron Rubber Flap Flange

Nodular Cast Iron check valve refers to the valve that automatically opens and closes the valve flap by relying on the flow of the medium itself to prevent the backflow of the medium, also known as check valve, check valve, reverse flow valve, and back pressure valve. The check valve is an automatic valve whose main function is to prevent the backflow of the medium, the reverse rotation of the pump and the driving motor, and the discharge of the medium in the container. Check valves may also be used on lines supplying auxiliary systems where pressure may rise above system pressure. Check valves can be mainly divided into swing check valves (rotating according to the center of gravity) and lift check valves (moving along the axis).

Nodular Cast Iron Check valves are mechanical valves that permit gases and liquids to flow in only one direction ,preventing proces flow from reversing .They are classified as one-way directional valves.Fluid flow in the desired direction opens the valve ,while back flow forces the valve closed.The mechanics of check valve operation are not complicated. Check valves work automatically and most dont need control by people or any external control.
