Emerson™ Butterfly Valve, Wafer Design, Seated, 6 in Nominal, Cast Iron Body, Electric Actuator
- One-piece, thin profile, disc stem provides minimum obstruction to flow, resulting in highest Cv, lowest pressure drops and best control characteristics
- Rounded polished disc edge gives full concentric sealing, lower torques, longer seat life and tight shut-off
- Triple function, resilient seat isolates body and stem from line media, provides droptight shut-off of line media at full-rated pressure and provides positive flange sealing, eliminating the need for flange gaskets
- Heavy duty, corrosion resistant top bushing provides upper stem support, absorbs actuator sideloading and extends valve cycle life
- Bi-directional, self-adjusting double V-cup stem seals prevent external contaminants from entering the valve
- Split body design enables easy field replacement of seat and disc/stem and permits direct mounting of Keystone actuators without the use of couplings or brackets
