Double Orifice Air Valve

Double Orifice Air Valve – Air Management for Water Systems

Air valves (air release, air/vacuum, and combination air valves) protect water transmission and distribution systems by automatically releasing accumulated air during operation and admitting air during pipeline draining—essential for preventing air locking, pressure surges, and pipeline collapse across African municipal water networks and irrigation systems.

From Egyptian Nile water distribution to South African mine dewatering systems, air valves prevent operational problems including reduced flow capacity, increased pumping costs, and destructive water hammer events. Proper air valve sizing and placement per AWWA standards ensures system efficiency and protects against negative pressure conditions during pump trips and filling operations common in areas with unstable power grids.
