Introduction. Non-Slam Check Valves are a specific type of check valve designed to eliminate the possibility of water hammer, a potentially damaging phenomenon that can occur in fluid systems when there is a sudden change in flow velocity. These valves are aptly named "non-slam" because they close before the reverse flow can begin, thus preventing the "slamming" …
