Automatic Fire Exhaust Valve

Product Introduction:
The automatic air vent is specifically designed for fire protection systems such as wet, dry/wet alternate, pre-action, recycling, foam spray, and foam storage tank systems in automatic sprinkler systems. Installed at the top of the system, it prevents air blockages and airlocks during system water filling and air venting. Once the system is filled with water, it automatically closes the air outlet; during system maintenance and water drainage, it automatically opens to inhale air, preventing negative pressure deformation and damage to the pipeline network.
