The PVC Breather Valve function is to make air inlet and outlet the system. PVC Air Evacuation Valve can automatically discharge a small amount of air accumulated in the pipeline under pressure, and automatically intake when the pipeline is under negative pressure. PVC Evacuation Valvesize from DN15 to DN50, connected with thread and flange. PVC Breather Valve protects system from pressure exceed and pressure vacuum. Vacuum Pressure Valve is used for corrosive medium.
