6. Ọrụ
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.
