DeZurik’s two 18” and three 14” PEC eccentric plug valves have been removed from service after over 60 years on the Intake Structure to the Primary Clarifiers at a Water Treatment Plant in Omaha, Nebraska. They are the PEC eccentric plug valves with the longest recorded service life. Over the past 60 years, these valves handled flows of 12 to 15 MGD and were cycled a couple times each day. The valves were originally installed when this portion of the plant was built in the 1950’s and have been replaced with new, automated DeZURIK Eccentric plug valves.
