Technical Specification

Non-slam Check Valves are designed and manufactured to ensure low leakage to international standards, Extensive base line laboratory testing (static and cycle testing) has been performed establishing critical design parameters necessary to achieve low emission sealing in the Cast Iron non-slam Checks, In-house testing procedure has been developed and is periodically performed to ensure that standard product design and manufacturing criteria consistently result in the cast iron check Valve meeting a maximum of leakage prior to shipment.
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.
