The check valve is to rely on the flow of the media itself and automatically opens and closes the valve flap, used to prevent the media back to the valve, also known as the water check valve, counterflow valve, and back pressure valve. The check valve is automatic, and its main role is to prevent media backflow, prevent the pump and drive motor reversal, and release container media.
“Check Valves” are the ones that permit fluid to move in one direction only. They prevent the backflow of water or other liquids. Brass is a soft metal that offers more corrosion resistance than traditional metals. Therefore, using brass in check valves makes them more sustainable and increases their life span. Hence, we can quote that “Brass check valves” are the best option to avoid backflow or restrict contamination in fluids.
