A Dual Plate Check Valve, also known as a Double Door Check Valve, is a type of non-return valve designed to prevent backflow in a piping system. It's called "dual plate" because it uses two spring-loaded plates (or discs) that open to allow forward flow and automatically close when the flow stops or reverses. When fluid (liquid or gas) flows in the desired direction, the pressure pushes the two plates open. If the flow slows down or reverses, the spring mechanism quickly snaps the plates shut, blocking reverse flow.
