Double Flange Butterfly Valve

Double Flange Butterfly Valve Manufacturer: FlowBiz Exports

The FlowBiz Double Flange Butterfly Valve is characterized by its heavy-duty body featuring integrated flanges at both ends. This design allows for independent bolting to each pipe flange, providing a secure, leak-proof connection that is ideal for dead-end service and high-velocity flow systems.

Key Features & Engineering Advantages

  • Integrally Molded Seat Liner: The seat is molded directly onto the body, ensuring outstanding dimensional stability. This prevents seat "bunching" or displacement during high-velocity flow, resulting in assured seat tightness over thousands of cycles.
  • Gasket-Free Installation: FlowBiz engineers have extended the seat liner to cover the flange contact faces. This innovative design eliminates the need for separate flange gaskets, reducing installation costs and removing a common potential leak path.
  • Bi-Directional Sealing: Provides a bubble-tight shut-off regardless of flow direction, allowing for versatile installation in complex piping layouts.
  • State-of-the-Art Engineering: Optimized for frequent ON/OFF operations, ensuring the valve remains "Fit & Forget" even in the most demanding utility and process lines.
  • Large Diameter Capability: With sizes available up to $1200\text{mm}$, we cater to municipal water mains, cooling water systems, and large-scale industrial effluent lines.

Strategic Industrial Applications

  • Water Distribution: Main isolation valves for municipal water supply and treatment plants.
