Product Description
Triple offset butterfly valves specification
* 1st Offset: It is accomplished by moving the centerline of the shaft away from the seat surface.
* 2nd Offset: It is accomplished by moving the centerline of the shaft offset from the centerline bore of the valve.
* 3rd Offset: It is accomplished by adjusting the cone angle created by the 1st and 2nd offset angles at some point downstream of
the valve in the center of the piping to the adjacent piping wall.
* By incorporating the 3 offsets into one design eliminates any risk of friction and jamming of the disc on the seat. This
increases valve life time, the driving torque is very low, in comparison with other types of valves
Triple offset butterfly valves specification:
* Anti-static
* Blow-out proof stem
* Fire safe API 607
* V type packing
* Zero leakage
* Ends: Wafer, Lug, Double flange.
* Uni-directional/Bi-directional sealing
* Operation: Lever, Gear, Electric, Pneumatic actuator
* Bare shaft with ISO 5211 top mounting flange (when specified
Applicable seat materials of triple offset butterfly valves
* Metal with Graphite
* Metal with PTFE
* Other materials can be supplied upon request
