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