DeZURIK’s APCO Swing Check Valves prevent the backflow of stormwater by closing before flow reversal, preventing slam and water hammer. The designs meet or exceed the current revision of AWWA standard C508. The APCO ASV air vacuum valves allow large volumes of air to be exhausted from or admitted into a pipeline as it is being filled or drained. Four of the 60-inch APCO brand CVS-6000 swing check valves and ASV air vacuum valves are installed at the Louis Armstrong New Orleans Airport Pump Station. This pump station directs stormwater away from the airport to protect against flooding damage during tropical storms. The valves are part of the extensive post-Katrina infrastructure modifications that are critical to the protection of the City of New Orleans and its transportation system. DeZURIK has extensive experience manufacturing large valves for water distribution, water treatment, wastewater collection and wastewater treatment. 320-259-2000; www.dezurik.com.
