Brass check valve is a type of valve that prevents medium backflow and has a wide range of application scenarios. The following are common application scenarios for brass check valves: 

1. Tap water pipeline: In tap water pipelines, some water plants, reservoirs, and other institutions require the use of check valves to prevent pollution. 

2. Industrial pipelines: In industries such as metallurgy, chemical engineering, construction, and power, brass check valves are commonly used to prevent medium backflow and protect equipment. 

3. Fire protection system: Brass check valves play a very important role in urban fire protection systems. In the fire protection system, if the brass check valve fails, it will cause the water flow to reverse, seriously affecting the fire protection work. 

4. Air conditioning ducts: Brass check valves also have important applications in air conditioning ducts. Due to the fact that the medium in the air conditioning system is gas, if the medium flows back, it will cause a decrease in equipment performance. Brass check valves can effectively solve this problem.
