Val-Matic’s wafer silent check valves have received certification to NSF/ANSI 61 for drinking water system components. Underwriters Laboratories (UL) provided certification of the Val-Matic product line after completion of all testing and verification of data. These check valves are designed for silent operation with low headloss in a compact wafer body. The valve’s short linear stroke and spring return action combine to close the valve prior to flow reversal, thus eliminating surges and waterhammer normally associated with sudden stoppage at reverse flow. They are available in sizes 2 in to 10 in and are WQA Certified Lead-Free.
