Triple-offset metal-seated butterfly valve
Review KEHUA triple-offset metal-seated butterfly valves. Confirm model-specific temperature limits, sealing direction, leakage acceptance and operating torque.
Butterfly Valves
Triple-offset metal-seated butterfly valve
Triple offset describes the sealing geometry, whereas metal seated describes the sealing interface. Obtain the offered section drawing and sealing-ring details, then agree shutoff direction, torque and test acceptance.
About the triple-offset metal-seated butterfly valve manufacturerThese are family-level options. Confirm the offered series rating and materials against its approved datasheet.
Sample catalogue reference
The figures describe the named catalogue construction. Size, pressure, temperature, material and end options are not interchangeable combinations; the maximum values do not apply simultaneously. Confirm the offered configuration, seat/seal compatibility, pressure–temperature limits and dimensions on its approved datasheet and drawing. The listed ranges summarize catalogue sizes, not every intermediate DN.

These are model- and class-specific examples. Not every size or end style is available in every configuration; final dimensions and ratings require an approved drawing and datasheet.
SERIES SELECTION
What must a triple-offset butterfly valve quotation confirm?
Request the offered section drawing to confirm triple-offset geometry and identify the metal-seat sealing arrangement, disc and seal materials. Agree pressure direction, test conditions and allowable shutoff leakage for the exact model, then review closing torque, thermal cycles and installation clearance. Do not transfer another configuration's acceptance or ratings to the proposed valve.

- Agree pressure direction, test conditions and allowable shutoff leakage.
- Review closing torque, thermal cycles and installation clearance; do not assume bidirectional sealing.
