The Seal principle of hard Seal Butterfly Valve triple offset
The Triple Offset Butterfly Valve Provides a bi-directional bubbletight shut-off.
This geometry ensures that the disc seal contacts the body seat only at the final shut-off
Position without rubbing or galling, providing atorque generated resilient seal with sufficient
"wedging" to ensure auniform seal contact.
