Frequently Asked Questions (B2B)
Q: What precautions should be taken when brazing SVD solder hand valves onto copper lines?
A: Wrap the valve body with a wet cloth during brazing to prevent overheating the internal nylon stem packing, and direct the flame away from the main valve housing.
Q: Why choose ODF solder hand valves over flare mechanical connections?
A: ODF solder connections create a permanent brazed joint with copper tubing, offering maximum leak integrity and vibration resistance in high-pressure commercial refrigeration systems.
Q: What OEM manufacturing and customization services does AIR DRAGON Ent. Ltd. offer?
A: AIR DRAGON Ent. Ltd. provides complete OEM support, including custom ODF sizing, private label handwheel branding, bulk export packaging, and volume pricing for equipment manufacturers.
