Description

A.R.I. S-021 is an ultra-compact, automatic Air Release Valve installed on pressurized raw, reclaimed and non-potable water transmission systems. The valve releases accumulated air - improving pipeline hydraulic efficiency by reducing head losses and improving flow. The unique body shape of the valve, enables a continuous air gap that separates the liquid from the sealing mechanism and helps to avoid deposits or blockage.

Product Features

  • Conical body shape & unique design - maximum air gap / minimum body length.
  • Continuous air gap - separates the liquid from the sealing mechanism.
  • Float assembly & sealing mechanism linkage - free movement, turbulence will not unseal the sealing mechanism.
  • Funnel-shaped lower body - residue matter falls back into the system pipeline.
  • Rolling seal - leak-free sealing over wide range of pressure differentials.
  • All parts are suitable for corrosive liquid and environment - non-corrosive and durable
  • Tap - releases pressure and drains valve prior to maintenance

Application Range

  • Size range 1” - 2”.
  • Sealing pressure range Sealing pressure range: 0.1 - 10 bar (PN10)
  • Testing pressure: 1.5 times maximum working pressure
  • Temperature Maximum working temperature: 60° C
  • Maximum intermittent temperature: 90° C

Installation:

  • Water with low concentrations of suspended solids:
  • Reclaimed & raw water pumps
  • Transmission pipelines with low concentrations of suspended solids in liquid
  • On liquid transmission pipelines
  • Upstream of filtration systems
