A check valve is also called a one-way valve. It only allows the medium to flow in one direction and is closed for reverse flow. The check valve achieves flow direction control by utilizing the medium flow's pressure and the reverse flow's force. This prevents the backflow of media. This kind of valve has a simple structure, is reliable, and has small pressure loss. Double-disc check valves suit various media, including liquids, gases, and steam.
