Metal-Seated Ball Valve

Description

1. Fixed Ball Design:

• For low/medium pressures and small diameters, the valve uses a trunnion-mounted ball for stability.

• For high pressures and large diameters, a support plate reinforces the structure to prevent deformation.

2. Fire-Safe Construction:

• Patented fire-resistant design (e.g., secondary metal seals) ensures zero leakage during fire events, complying with API 607/API 6FA standards.

3. Blowout-Proof Stem:

• The stem is mechanically locked to prevent ejection under extreme pressure, enhancing safety.

4. Anti-Static Device:

• A spring-loaded mechanism grounds static electricity between the ball and stem, eliminating spark risks in flammable environments.

5. Emergency Sealant Injection:

• Sealant ports allow temporary sealing of damaged seats/ball surfaces during emergencies, ensuring continued operation.

6. Bidirectional Sealing:

• The valve seals equally effectively in both flow directions, adapting to complex pipeline layouts.
