Trait and purpose:
Hard Seal Butterfly Valve triple offset series are Unique VALVE 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 bubble tight 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 a torque generated resilient seal with sufficient "wedging" to ensure a uniform seal contact.
