5. సంస్థాపన
Follow these steps for proper installation of the Zurn 34-850TXL ball valve:
- తయారీ: Ensure the system is completely shut off, depressurized, and drained. Clean the pipe threads of any debris.
- థ్రెడ్ సీలెంట్: Apply an appropriate thread sealant (e.g., PTFE tape or pipe dope) to the male pipe threads. Ensure the sealant is compatible with the system fluid and valve materials.
- కనెక్షన్: Thread the valve onto the pipe. Use a wrench on the valve body flats to tighten. అతిగా బిగించవద్దు, as this can damage the valve or pipe threads. Avoid applying torque to the valve handle.
- దిశ: The valve can be installed in any orientation. Ensure the handle has sufficient clearance for full quarter-turn operation.
- Tapped Port (if applicable): If utilizing the tapped port, ensure proper connection and sealing of any auxiliary devices (e.g., pressure gauges, drain valves).
- సిస్టమ్ ప్రారంభ: Slowly repressurize the system and check for leaks at all connections.

6. ఆపరేషన్
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.
- To Open the Valve: Rotate the handle until it is parallel with the pipeline. This indicates a full port opening, allowing maximum flow.
- To Close the Valve: 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. నిర్వహణ
The Zurn 34-850TXL ball valve is designed for minimal maintenance. Regular inspection is recommended to ensure optimal performance.
- తనిఖీ: Periodically check for any signs of leaks around the valve body or connections. Inspect the handle for damage or looseness.
- శుభ్రపరచడం: Keep the exterior of the valve clean. Avoid using harsh chemicals that could damage the bronze finish or internal components.
- సరళత: The valve is designed with self-lubricating components and typically does not require external lubrication.
- మరమ్మత్తు: 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.
