A split body thin disc valve for high flow and modulating serviceFigure 990 – Wafer body designFigure 920 – Lugged body design

Features

• bstruction 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 drop-tight 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.
