Key features/benefits
While not a valve in the traditional sense, check valves serve an important application—namely to prevent f low in one direction while allowing it in the other. A check valve is self-actuated and designed to prevent f luid from flowing back into the system (prevent reverse flow). Real-life applications include preventing backflow into an injection line or into a pump. The f luid flow opens the valve by forcing a disk or ball in one direction. When the flow stops, the disk or ball is seated and closes the valve. They can be installed in horizontal or vertical upward flow piping.
