ARI S-021 Automatic Air Release Valve for Reclaimed and Non-Potable Water

ARI,S-021,Automatic,Air,Release,Valve,Reclaimed,Non-Potable,WaterThe presence of air in a reclaimed and non-potable water system can reduce the effective cross sectional flow area, resulting in increased pressure loss and deceased flow. Unwanted air may also cause water hammer and metering inaccuracies, while hastening corrosion. The ARI S-021 automatic air release valve discharges accumulated air from the system while it is under pressure.

Applications

  • Reclaimed water
  • Raw water
  • Effluent water
  • Water with suspended solids
  • Coolant water

Main Features

  • Working pressure range: 0.2-10 bar Testing pressure: 16 bar
  • Working Temperature: 60° C.
    Maximum short-term temperature: 90° C.
  • Body made of composite plastic material, resistant to corrosion.
  • Internal metal parts are made of corrosion-resistant stainless steel.
  • Floats are made of composite materials.
  • Flexible rolling seal provides smooth positive opening, closing, and leak-free sealing over a wide range of pressure differentials.
  • 1/8" threaded discharge outlet enables removal of excess fluids.
  • Drainage tap with ball valve is provided.
  • The valve’s unique design prevents any contact between the liquid and the sealing mechanism by creating an air gap at the top of the valve. This air gap is guaranteed even under extreme conditions.
  • Spring-loaded float and seal plug connection assures that vibrations of the lower float will not unseal the air release orifice of the air valve
  • Funnel-shaped lower body automatically drains the liquid into the system, allowing valve internals to remain clean and unobstructed.

Ordering:
Upon ordering, please specify: model, size, working pressure, threads/flanges standard and type of liquid.
