Non Return Valves Wafer Double Door Flap Check Valve NRV

Check valves also known as dual plate 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.
