Double Offset Butterfly Valve

Double Offset Butterfly Valve Manufacturer: FlowBiz Exports

The FlowBiz Double Offset Butterfly Valve features a unique geometry where the shaft is offset from the centerline of the seat and the centerline of the pipe. This "double eccentricity" allows the disc to "cam" into the seat, significantly reducing friction during opening and closing. This design ensures lower operating torque and a much longer life for the sealing surfaces.

Key Features & Advantages

  • Reduced Friction & Wear: The double-offset geometry allows the disc to move away from the seat almost immediately upon opening. This minimizes seat wear and prevents "rubbing," which is the leading cause of failure in standard butterfly valves.
  • Replaceable Seat Design: Unlike many high-performance valves, FlowBiz designs feature an easily accessible and replaceable seat. This allows for simple field maintenance without needing to replace the entire valve body.
  • Low Operating Torque: Because the disc doesn't rub against the seat throughout its travel, it requires significantly less force to actuate, allowing for smaller, more cost-effective pneumatic or electric actuators.
  • Bubble-Tight Shut-Off: Available with advanced polymer seats for zero-leakage in liquid/gas service or metal seats for high-temperature and abrasive applications.
  • Bi-Directional Sealing: Engineered to maintain seal integrity regardless of the flow direction, providing flexibility in pipeline installation.
