Description
The double disc check valve is a one-way valve, also known as double door check valve, double flap check valve or double plate check valve. It allows fluid to flow in one direction and cannot flow in the other direction. Check valves of various sizes, shapes and types are available, and they are usually self-adjusting, meaning that the flow of fluid itself often controls the opening and closing of the check valve.
