Product Overview: PANS Full Metal-Seated Bi-Directional Butterfly Valve

The PANS Full Metal-Seated Bi-Directional Butterfly Valve features a “Metal-to-Metal Seat Ring” design, ideal for frequent operations and high sealing requirements. Key features include:

1. Metal-to-Metal Seat Ring Both the disc and seat sealing rings are made of metal with hardfaced treatment, ensuring reliable sealing performance and extended lifespan under frequent use.

2. Bi-Directional Zero-Leakage Design This valve series meets bi-directional zero-leakage standards, providing leak-free sealing in both directions, suitable for high-sealing applications.

3. Double Safety Structure The valve includes separate thrust rings on both sides of the disc to prevent deformation and misalignment caused by fluid pressure and temperature, ensuring reliable operation.

4. Anti-Blowout Stem Features an anti-blowout stem design to prevent accidental stem ejection, enhancing safety.

5. No Dead Zone Design Using a triple-eccentric structure, the valve avoids common “opening jump area” issues, allowing smooth regulation from nearly 0 to 90 degrees.

6. Forged Alloy Steel Seat Ring The seat ring is made of forged alloy steel, offering excellent wear resistance and high temperature and pressure tolerance for long-term reliability.

7. Replaceable Sealing Rings Both disc and seat sealing rings are replaceable, simplifying maintenance and reducing costs.

8. Evenly Fixed Structure The sealing ring is fixed with evenly distributed bolts to prevent leakage or loosening.

9. Fire-Safe Design The metal-seated structure meets API 607 fire safety standards, enhancing safety.

10. Live Loaded Packing System Equipped with a live loaded packing system, ensuring a maximum leakage rate of ≤20 PPM and extending maintenance-free periods.
