Brazing Air Conditioner Stop Valve
Air Conditioner Stop Valve Description
- Flame brazing is currently the most common brazing method in the field of brazing, and the other is induction brazing.
- The advantage of flame brazing is that it is easy to deploy, and because the temperature requirements for brazing are not high, there is a wide range of gas options for brazing, such as low-cost natural gas being the most extensive choice.
- The disadvantage is that there is a flame, and some customers have safety concerns, but our automatic flame brazing machine is equipped with a nitrogen fire extinguishing system and 3 anti-backlash valves. Safety is always our first priority.
