Design Feature

Triple eccentric design and the cone shaped sealing mechanism for Triple Offset Butterfly Valves

1 - Zero leakage and tight shut-off

2 - Fire safe triple eccentric butterfly valve

3 - Advantage of the geometric construction

4 - Low friction between a disc and a seat

5 - Low Torque enables the compact actuator and long lifetime

6 - Sealing mechanism is designed for heat-expansion

7 - Wide range of application from the cryogenic to high temperature

8 - Unique packing material provides fugitive emission packing

9 - Super long usage life

10 - Double block and bleed

11 - Blowout-proof stem

1st Offset

To have positive sealing and increase sealing capacity, the axis of the shaft is placed behind The center line of sealing point on our Triple Offset Butterfly Valves.
