High-Performance Double Offset Disc Butterfly Valve
High-Performance Double Offset Disc Butterfly Valve
FlowBiz is a premier manufacturer of Double Offset (Eccentric Design) Butterfly Valves, widely recognized in the industry as "High-Performance Butterfly Valves." Engineered for excellence, these valves are designed to handle high-pressure environments and frequent ON/OFF operations in large-scale pipelines.
Available in both Manual Gear and Handle-operated configurations, our valves utilize state-of-the-art geometry to ensure smooth flow control and long-term durability.
The Science of the Double Offset:
FlowBiz engineers utilize two specific offsets to create a unique "cam action," allowing the disc to lift off the seat immediately upon opening to reduce friction:
- Primary Offset: The shaft axis is positioned behind the center-line of the sealing point (disc-to-seat).
- Secondary Offset: The shaft axis is eccentric to the vertical center of the valve and pipeline.
The Result: A valve that operates with lower torque, experiences minimal seat wear, and provides a much tighter seal than standard zero-offset styles.
