Abstracts: The main function of check valves is to close upon forward-flow stoppage and prevent or minimize the development of reverse flow. This function helps to protect pumps and systems from damage caused by reverse flow. Check valves are also used to isolate areas of plants, such as nuclear power plants, from over-pressurizing or being contaminated. The dual Plate Check Valve is an all-purpose non return valve that is much stronger, lighter in weight and smaller in size compared to a conventional swing check valve or life check valve.
