Premium Double Flange Triple Offset Butterfly Valve by CTGV
The Double Flange Triple Offset Butterfly Valve is a high-performance valve designed for critical applications requiring zero leakage, high pressure, and extreme temperature resistance. It combines the compact design of a butterfly valve with the sealing reliability of a globe or gate valve, making it ideal for oil & gas, petrochemical, power plants, and steam systems.
Zero Leakage & Bubble-Tight Shutoff
The triple offset design ensures a metal-to-metal seal between the disc and seat, eliminating reliance on elastomers.
Ideal for critical applications (e.g., steam, hydrocarbons, chemicals) where leakage is unacceptable.
Low Operating Torque & Reduced Wear
The cammed action of the disc minimizes friction during operation, reducing wear on the seat and disc.
Requires less actuation force, lowering costs for actuators and energy consumption.
High-Pressure & High-Temperature Capability
Suitable for Class 600 to Class 1500 and temperatures up to 1,000°F (538°C).
Performs well in steam, oil & gas, and refinery applications.
Double Flange Design for Secure Installation
Flanged ends provide a strong, leak-proof connection to pipelines, reducing the risk of gasket blowout.
Easier to bolt directly to piping systems without additional adapters.
Long Service Life & Minimal Maintenance
Hardened stainless steel or Stellite seating surfaces resist erosion and corrosion.
No need for frequent adjustments or replacements like soft-seated valves.
Flanged Connection: Ensures a stable, easy-to-install valve configuration.
