6. Provoz

The Zurn 34-850TXL is a quarter-turn ball valve, meaning it requires a 90-degree rotation of the handle to go from fully open to fully closed, or vice versa.

  • Otevření ventilu: Rotate the handle until it is parallel with the pipeline. This indicates a full port opening, allowing maximum flow.
  • Zavření ventilu: Rotate the handle until it is perpendicular to the pipeline. This indicates the valve is fully closed, stopping flow.
  • Throttling/Balancing: The valve can be partially opened to regulate flow. For precise balancing, specialized balancing valves may be more suitable.

7. Údržba

The Zurn 34-850TXL ball valve is designed for minimal maintenance. Regular inspection is recommended to ensure optimal performance.

  • Inspekce: Periodically check for any signs of leaks around the valve body or connections. Inspect the handle for damage or looseness.
  • Čištění: Keep the exterior of the valve clean. Avoid using harsh chemicals that could damage the bronze finish or internal components.
  • Mazání: The valve is designed with self-lubricating components and typically does not require external lubrication.
  • Opravit: In case of persistent leaks or operational issues, it is recommended to replace the valve. Attempting to repair internal components may void any warranty and could compromise the valve's integrity.
