Description

The actuated Butterfly Valve is comprised of an actuator, linkage and valve body. The valve size and type, Cv ratings and CloseOff pressure determine the type of actuator series used. This correlation is in the Valve Selection Chart. Valves are Class 125 bubble tight to 200 PSI and are sized from 2 to 12 inches. They feature a cast iron body with aluminum bronze disc and EPDM seat. The patent pending S-shaped disc improves the Cv rating and enhances the flow capacity. The result is minimum turbulence. The unique Touch Seat design (U.S. Patent No. 4,605,201) requires reduced torque to seat the disc. Connections are full lug, drilled and tapped.
