Frequently Asked Questions:

1. Q: Can this valve handle variable flow conditions in HVAC systems?
   A: Yes, the balanced diaphragm design maintains precise pressure control across 10-100% flow rate variations.
2. Q: Is the valve suitable for both hot and cold water applications?
   A: Absolutely, the standard version operates reliably in 0-80°C environments. High-temperature models are available upon request.
3. Q: How often does the strainer require cleaning?
   A: Maintenance intervals depend on water quality. We recommend quarterly inspection during initial operation, with adjustments based on observed debris accumulation.
4. Q: Can the outlet pressure be adjusted while the system is operating?
   A: Yes, the external adjustment knob allows pressure setting changes without shutting down the pipeline.
5. Q: What is the typical delivery lead time for DN150 valves?
   A: Standard sizes ship within 2 weeks from our Shanghai warehouse. Contact sales for expedited options.
6. Q: Does the valve require vertical installation orientation?
   A: Horizontal installation is acceptable, but vertical mounting with upward flow direction optimizes performance.
