Description
Key Features of Welded Ball Valves
- Precision-Machined Ball: Ensures low operating torque and smooth valve operation.
- High-Performance Sealing Materials: Imported PTFE+C and FKM seals provide higher temperature tolerance and extended valve lifespan.
- Innovative Stem Seal Design: Enables pressure-maintained replacement for easier maintenance without shutting down the system.
- Advanced Anti-Corrosion Surface Treatment: Protects against rust and corrosion in industrial environments.
Typical Applications
- Shut-off and control in urban district heating pipelines and heat exchanger units.
- Branch pipelines in power plants and industrial facilities.
- Hot water distribution in steel mills and other industrial heating systems.
