Swing VS Non Slam Check Valve: Which one to Choose?

This video explains the differences between swing check valves and non-slam check valves, and how to select the right type for industrial piping systems. It discusses how swing check valves can cause issues like water hammer and allows for potential compressor reverse flow or pump pulsation due to their slamming shut mechanism.

Non-slam check valves are presented as an alternative to address these problems through controlled closing. Key applications where non-slam valves excel are highlighted, such as compressor discharge lines, centrifugal pump discharge, and reciprocating pump systems prone to pulsation.
Engineers will learn how identifying process requirements and reviewing P&ID diagrams can reveal if a system's characteristics call for a standard swing valve or advanced non-slam design.
The right check valve selection is emphasized as critical to ensuring process safety and reliability while preventing downtime and repairs.
