Double Offset Wafer Butterfly Valve, Triple Eccentric Butterfly Valve Metal Seated

Double Offset Wafer Butterfly Valve Triple Eccentric Metal Seated




The triple eccentric butterfly valve, which makes use of a metal seat, is, therefore, able to withstand a greater amount of pressure, compared to a resilient seated butterfly valve. The seal of the eccentric disc could be either metal/Graphite multi-layer design or fully metal-to-metal design. The multi-layer design could achieve zero leakage and simple maintenance, while the metal-to-metal design is more reliable in higher temperature and pressure. Basically speaking, the triple eccentric butterfly valve is both applied in shutoff or throttling service.

Wafer type is the common style of a butterfly valve and is less expensive than the lug type. The wafer butterfly valve is installed between two flanges. The valve is kept in place by using bolts or studs and nuts from flange to flange. This type of installation, of course, makes it impossible to disconnect just one side of the piping system from the valve.
