Triple Offset Design: The "Zero Leakage" Engineering
The Triple Offset Butterfly Valve (TOV) represents the pinnacle of valve geometry. Unlike concentric or double offset designs, the TOV incorporates three distinct offsets that eliminate seat friction and wear:
- First Offset: The shaft is located behind the sealing surface.
- Second Offset: The shaft is located to one side of the pipe centerline.
- Third Offset (The Geometric Innovation): The seat and disc seal are machined into an inclined conical profile.
The Result: Frictionless Sealing
This geometry creates a "cam-action" closure. The disc only contacts the seat at the final point of closing. This eliminates rubbing, reduces operating torque, and allows for a high-integrity metal-to-metal seal that is ideal for high-temperature and fire-safe applications.
Technical Specifications (2026 Wafer Series)
The Wafer Type design is preferred for its compact "face-to-face" dimensions, making it easy to install between existing pipe flanges while saving significant weight and space.

Strategic Industrial Applications
1. Oil & Gas (Refineries & Petrochemicals)
Essential for high-temperature hydrocarbon service where fire-safe certification (API 607) is a mandatory safety requirement.
2. Power Generation & Steam Service
The metal-to-metal seat thrives in high-pressure steam lines and condensate systems where soft seats would melt or degrade.
3. Chemical Processing
The triple offset design handles aggressive chemicals and light vacuum applications with superior sealing integrity.
4. Cryogenic Service
Engineered with specialized materials to maintain a bubble-tight seal in liquid nitrogen and LNG applications.
