Traits and purposes
Hard Seal triple offset Butterfly Valve 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 Triple Offset Butterfly Valves
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 contact.
