Urban roadway high-point air venting, cross-country water transmission lines under asphalt roads, residential subdivision water distribution, and airport runway utility corridors across Baghdad, Erbil, Basra, Sulaymaniyah, and Najaf.
Underground Direct-Burial Air Valve Packages provide the most cost-effective and space-efficient hydraulic air management solution for municipal water distribution networks and cross-country transmission pipelines across Iraq. In dense urban street networks in Baghdad, Erbil, Basra, and Kirkuk, constructing reinforced concrete manholes for every air valve installation requires massive excavation, expensive shuttering, and asphalt restoration, while underground chambers frequently fill with contaminated street floodwaters that can enter standard air valves. Indus direct-burial air valve packages eliminate the concrete chamber entirely by housing the air valve assembly inside an engineered telescopic burial shroud topped by a street-level surface box.
The assembly features a high-performance triple-function kinetic air valve coupled directly to an integrated isolating butterfly or gate valve. An innovative automatic drain valve at the base expels any accumulated condensation or flood water into surrounding gravel backfill, while an intake check snorkel fitted with fine insect/dust mesh ensures that air drawn in during vacuum conditions is clean and free of desert dust. The telescopic riser adjusts easily to match final road paving levels without cutting or welding.
Topped by a Class D400 heavy-duty ductile iron surface box rated for 40-ton highway wheel loads, maintenance crews can isolate the air valve and inspect the mechanism from the street surface using universal operating keys. Staged at our Erbil Heavy Yard, Baghdad Central Logistics Depot, and Basra Port Hub, Indus supplies complete direct-burial air valve sets with full EN 10204 3.1 inspection certification.
The air valve is enclosed inside an engineered polyethylene or ductile iron protective shroud with an elevated air snorkel located directly beneath the surface box lid. A floating one-way check mechanism in the snorkel seals shut if surface floodwater inundates the street box, preventing external contamination from entering the drinking water main.
The isolating valve is connected to a square drive cap located directly below the street box cover. Technicians use a standard municipal T-key to rotate the spindle from street level, shutting off water to the air valve in seconds without excavation.
Yes. The surface box is certified to Class D400 (40-ton load capacity per EN 124), designed to safely support continuous heavy multi-axle freight traffic on Iraqi highways.
