Characteristics
This air valve adopted flange-connected, installed firmly and sealed well, suitable for large-diameter, medium and high-pressure pipelines, not easy to fall off and leak water.

Advantages
1.Firm connection and reliable sealing
The pressure is higher, and it is not easy to loosen and leak
Suitable for large-diameter, medium and high-pressure pipeline networks, safer than threaded exhaust valves
2.High exhaust efficiency, no suffocation
Single port large channel, rapid and large exhaust during pipeline water injection
Continuous micro exhaust during operation to eliminate air resistance and water hammer and ensure stable water pressure
3.Both exhaust and negative pressure protection
Normal exhaust
When the pipeline is under negative pressure, it will automatically air in to prevent the pipeline from being sucked and damaged.
Packing
