S-021 |Automatic Air Valve - Raw, Reclaimed & Non-potable Water
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
