Silent or Non Slam Check Valve is the valve of choice in applications when silent operation and cost are of major concern. Its short linear stroke and spring return action combine to close the valve prior to flow reversal. This effectively eliminates the shock and water hammer normally associated with the sudden stoppage of a reverse flow. Its silent operation and low purchase price have made it a favorite of engineers in clear liquid applications.
