Triple Offer Butterfly Valve

GTR series triple offset metal seat butterfly valves offer bi-directional, bubble-tight shut-off due to their unique geometry. The valve features three offsets: the first offsets the stem, the second offsets the seat surface's center line from the pipe, and the third uses an inclined cone to eliminate rubbing. This design enhances sealing and durability, requiring minimal maintenance. The angle of contact provides effective sealing with low torque, ensuring efficient transmission of actuator force to the seat parts.
