DeZURIK manufactures the following styles of butterfly valves :
AWWA Butterfly Valves are used for shutoff on clean water and gases. They are a resilient seated butterfly valve that meets the requirements of AWWA C504 and C516 standards. AWWA Butterfly Valves are available in sizes from 3-144"" (80-3600mm).High Performance Butterfly Valves are used for everything from general service applications to viscous and corrosive liquids; corrosive gases; and steam. These ASME Class 150 & 300 valves are available with PTFE seats, Dual Seats and Metal seats to handle temperatures up to 700°F (370°C) or higher on application.Uninterrupted Seat Resilient-Seated Butterfly Valves are used handle a wide variety of liquids and gasses. They provide bi-directional shutoff to the full rating of the valve and can be used in dead-end service without requiring downstream flanges. The Uninterruped Seat Butterfly Valve is an excellent choice for continuous modulating control, or for extended service applications such as high cycle and higher pressures 250 psi (1720 kPa) in 2-20” sizes, with 24-26” sizes to 175 psi (1210 kPa).On-Center Resilient Seated Butterfly Valves are used wide variety of liquids and gases in general service applications. These butterfly valves provide bi-directional shutoff to the full rating of the valve and can be used on dead end service with downstream flange attached. The On-Center Resilient Seated Butterfly Valve can handle pressures up to 175 psi (1210 kPa) in 2-12” sizes and to 150 psi (1030 kPa) in 14-48” sizes.
