Frequently Asked Questions (B2B)

Q: What installation precautions should service engineers take when connecting flare hand valves?
A: Ensure copper tube ends are cleanly deburred and flared with a standard 45-degree tool. Apply a drop of refrigeration oil to the flare face and tighten with a torque wrench to prevent thread distortion.
Q: How does the PTFE packing gland prevent stem leaks during temperature fluctuations?
A: High-density PTFE maintains elastic memory and thermal tolerance across extreme cold and ambient ranges, maintaining continuous compression against the brass stem during thermal cycling.
