| Check valves have a disc, ball, or plates that open when forward flow starts in the pipeline. When pressure drops, either gravity, back pressure, or a mechanical spring forces the disc back against its seat to prevent reversal of flow (backflow). Select check valve type based on process application requirements, installation, and ease of maintenance. |
