Double Eccentric Butterfly ValveWe make double eccentric type butterfly valves with EPDM, NBR, PTFE soft sealing design, and hard sealing design available for high temperature and high pressure application. We also supply concentric and triple offset design butterfly valves. The pressure can be up to 10.0MPa (Class 600#) for hard sealing design. Butterfly valves can come in three body types, lugged, wafer and flanged. Wafer style valves are more common. They are typically installed between two flanges using bolts or studs and nuts. Lug style valves are also installed between two flanges but with a separate set of bolts for each flange. The lugged style setup makes it possible to remove one side of the piping while the other remains intact.
