A.R.I. S-020 HC VB is a high-capacity, Automatic Air Release & Vacuum Breaker Valve Series installed on pressurized wastewater transmission systems. The valve releases accumulated air, optimizing pipeline hydraulic efficiency by reducing head losses, improving flow and opening to allow air intake, to protect the system from vacuum conditions. The unique body shape of the valve, enables a continuous air gap that separates the wastewater from the sealing mechanism and helps to avoid deposits or blockage.
