Air Release Vacuum Breaker Valve Description:

The air release valves will be installed at sections of the pipeline
where air pockets would be formed.


The valves shall be of robust construction of double orifices with
an integral isolating valve and

flanged base for connection to a valve stem that connects the air valve to the main pipeline.

The bore leading to the flange base shall be in accordance to the size of the main pipeline and the
expected accumulation of air.


Competitive Advantage:

DESIGN STANDARDS

• Coating Powder Epoxy Min. 250 micron
• Three Way Functioning:
- Release of large volumes of air during pipeline fill.
- Allows in flows of large volumes of air when pipe is emptied.
- Release of air under pressure
• Low Maintenance
• Working pressure Min. 0.1 bar Max. 16 bar
• Hydraulic test performed under 1.5xPN pressure

Install:


REMARKS & APPLICATIONS
• For water (Not sewage) and neutral liquids.
• Nominal Pressure: PN 16/25 & PN 25/40
• Working Temperature: -10˚C to 120˚C
