ARI D-040 Combination Air Valve

ARI D-040 Combination Air Valve

The ARI D-040 is a combination air valve. It's reliable operation reduces water hammer incidents. The dynamic design allows high velocity air discharge, up to 0.8 bar differential pressure; Preventing premature closing. Lightweight, small dimensions, simple and reliable structure. The body is made of high strength plastic, and all operating parts are made of specially selected corrosion resistant materials. The drainage outlets enables removal of excess fluids.

The air release mechanism uses the A.R.I patented, Rolling Seal Mechanism which:

  • Dramatically reduces the possibility of obstruction by debris.
  • Discharges high air flow rates up to 160 m3/Hr.
  • One size orifice for a wide pressure range (up to 16 bar).
  • Self cleaning mechanism.

Working pressure range: 3/4", 1": 0.2-10 bar, 2": 0.2-16 bar.

Available in 3/4" (20mm), 1" (25mm), 2" (50mm), BSPT threaded.

D-020 combination air valve sewage

D-020 combination air valve sewage

Guarantees complete separation of the liquid from the sealing mechanism by creating an air gap at the top of the valve.

  • The air gap, guaranteed even under extreme conditions, is achieved by a conical body shape that maintains maximum distance between the liquid and the Sealing Mechanism; while obtaining minimum body length.
  • Spring loaded joint between the stem and the upper float, to ensure that vibrations of the lower float will not unseal the automatic valve. Release of air will occur only after the accumulation of enough air.
  • Funnel-shaped lower body ensures that the residue sewage matter will sink to the system and be carried away.
  • Self cleaning Rolling Seal Mechanism.
