Design Features:
AWWA butterfly valves meet the requirements of AWWA C504 standards. They are used for shut off of clean and dirty water and gases. Offset disc design, corrosion-resistant shaft, stainless steel disc edge, and self-compensating shaft seals are features on all AWWA butterfly valves. Molded-in body seat with disc locators provides positive sealing and longer seat life on sizes 3 - 20" (80 - 500mm). Large AWWA butterfly valves, 24" and larger (600mm and larger) feature adjustable, replaceable seat, non-hollow disc structure and rubber seat retained within a dovetail groove in the valve body and locked in place by an epoxy wedge.
