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.
