Butterfly Valves
AWWA Butterfly Valves (BAW)
DESIGN FEATURES:
DeZURIK AWWA butterfly valves meet the requirements of AWWA C504 standards. They are used for shutoff 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 DeZURIK 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.
SPECIAL CONSTRUCTION:
Square and rectangular AWWA butterfly valves are designed in a variety of sizes for square/rectangular configurations. Specially designed packages for Pump Check control applications are also available.
High Performance Butterfly Valves (BHP)
DESIGN FEATURES:
DeZURIK High Performance Butterfly Valves (BHP) are designed for critical applications in chemical, hydrocarbon processing, pulp & paper, water/wastewater and HVAC industries. They provide exceptionally long and trouble-free service life, reducing total cost of ownership. DeZURIK BHP valves are rigorously tested to meet demanding industry performance requirements. High Performance Butterfly Valves are designed for shutoff and throttling control of liquids and gas. The dynamic PTFE seat provides bubble-tight shutoff in both directions. The single offset disc design provides lower torque and longer cycle life. NACE trim is available.
SPECIAL APPLICATION:
