Trait and purpose
Hard Seal Butterfly Valve triple offset series are our company's leading products,
Which are used in such fields as metallurgy, light industry, electric power, petrochemistry,
Coal gas channel etc.
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.
