Frictionless Operation: Triple offset design ensures disc disengages from seat instantly upon opening, minimizing seal wear
Bidirectional Zero Leakage: Metal sealing achieves bubble-tight shut-off in both directions per 598
Extreme Temperature Range: Operates from -196 degree C cryogenic to 550degree C high temperature, covering diverse thermal conditions
Compact & Lightweight: Short face-to-face dimension and light weight save installation space compared to gate valves
Long Seal Life: Laminated stainless steel + graphite seat offers excellent wear and corrosion resistance
Fire-Safe Design: All-metal construction with no soft parts, compliant with 607 fire-safe standard
Low Operating Torque: Triple offset geometry significantly reduces opening/closing torque for easy actuation
Field Maintainable: Seal ring can be replaced on-site without removing the entire valve, lowering maintenance cost
Severe Service Ready: Suited for high temperature, high pressure, corrosive/abrasive media, and LNG cryogenic services across industries
Worm gear reducer multiplies handwheel torque for effortless operation; built-in self-locking holds any position securely without extra brakes, ideal for medium-large sizes and frequent throttling.

Product Q&A
Q:What is a triple offset butterfly valve?
A:
A triple offset butterfly valve adds a third offset -an angular cone axis offset to the double offset design. This allows the disc to move without friction against the seat for most of the stroke, contacting only at the final closure point, enabling metal to metal zero leakage sealing
Q:What are the main advantages?
A:
Key advantages include: friction free operation reducing wear; bidirectional bubble tight sealing; wide temperature range (-196C to 815C); and suitability for high temperature, high pressure, corrosive, and abrasive media applications.
Q:Can triple offset butterfly valves achieve bidirectional sealing?
A:
Yes. Advanced designs use a spring loaded adjusting ring to compensate for shaft elastic deformation under pressure, enabling reliable bidirectional sealing. Forward pressure increases sealing tightness; reverse pressure is compensated by spring stored energy
Q:What leakage class can be achieved?
A:
With metal to metal seating, they achieve Class VI bubble tight shut off per 598/ISO 5208.
Q:What temperature range can they handle?
A:
They operate from cryogenic -196C (LNG service) up to 815C, far exceeding ordinary butterfly valves.
