Metal Seated Butterfly Valves

Metal Seated Butterfly Valve Manufacturer: FlowBiz Exports

The FlowBiz Metal Seated Butterfly Valve is engineered for high-performance service. Unlike resilient seated valves that use rubber or polymers, these valves utilize a spherical disc design with a metal-to-metal replaceable seat. This allows the valve to maintain structural integrity and a high degree of sealing (Leakage Class VI) at temperatures ranging from cryogenic levels up to $400^{\circ}\text{C}$.

Key Features & Advantages

  • High-Temperature Performance: The metal-to-metal seating surface is immune to the melting or degradation issues common in soft-seated valves, making it ideal for superheated steam and hot gas.
  • Anti-Leakage Design: Despite being all-metal, the precision-machined spherical disc ensures a tight shut-off, meeting ASME Class VI leakage standards.
  • Long Service Life: The rugged construction is highly resistant to erosion from abrasive slurries, high-velocity steam, and fly ash.
  • Replaceable Seat: FlowBiz valves feature a replaceable seat design, allowing for economical maintenance and extending the total life of the valve body.
  • Versatile Material Range: Available in various grades of Stainless Steel (304/316/L) to handle corrosive chemical environments and oxidation at high temperatures.
