Description
High-Performance Offset Disc Butterfly Valve - Double Flange
FlowBiz is a premier manufacturer of Double Eccentric (Double Offset) Butterfly Valves designed for high-precision flow control. Our valves are engineered to provide superior sealing and durability in demanding industrial environments, specifically for the on/off control of gases and liquids.
Whether you are operating in offshore power, marine, chemical processing, or petrochemical industries, FlowBiz delivers a product that balances longevity with ease of maintenance.
The Double Eccentric Advantage
Unlike standard concentric valves, our double offset design features a shaft that is offset from the center of the disc and the center of the valve body. This geometry:
- Minimizes Friction: The disc releases from the seat immediately upon opening, reducing wear and tear.
- Tight Sealing: Achieves a cam-like action that ensures a tight, bubble-free shut-off.
- Extended Service Life: Lower operating torque leads to a longer lifespan for both the valve and the actuator.
Key Product Features
- Versatile Seating: Available with Polymer (for smooth operation and chemical resistance) or Metal (for high-temperature/high-pressure) seats.
- Easy Maintenance: The seat is designed to be easily accessible and replaceable without specialized tools, reducing downtime.
- Standardized Geometry: All end connections follow international standards for hassle-free installation.
- Size Range: Comprehensive sizing from 2 ½ inches (65mm) to 48 inches (1200mm).
Technical Specifications & Standard Compliance
Our manufacturing process adheres to the world’s most stringent engineering benchmarks to ensure safety and performance.
