Common technical questions from enquiries we receive, answered by Supreme Valves India.
What types of check valves do you manufacture?
Swing check, dual plate wafer check, lift check, non-slam/silent check, ball check, and tilting disc check valves.
When should I use a non-slam check valve?
Non-slam (axial flow / silent) check valves are recommended for pump discharge lines where water hammer is a concern. The spring-assisted disc closes before flow reverses, preventing slam and pressure surge.
