African Valve is a trusted Dual Plate Check Valve Supplier in Angola. Dual Plate Check Valve designed to provide flow in one direction and close rapidly when back-flow occurs. Dual Disc responds automatically to block flowing fluid in one direction and prevents reverse flow.The unique design of the dual plate check valve allows for a more compact and lightweight construction compared to traditional swing check valves. 

When the fluid flows in the desired direction, it exerts pressure on the upstream side of the valve plates. This pressure forces the plates to pivot away from the flow path, allowing the fluid to pass through the valve with minimal resistance. However, when a reversal in flow or back pressure occurs, the fluid exerts force on the downstream side of the plates, causing them to quickly close and create a barrier that prevents any backflow from occurring. These valves offer several advantages over other check valve designs, including compact size, reduced pressure drop, and improved sealing capabilities.
