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
The Air Release Valve shall maintain closed position to prevent the
loss of water by the positive
seating of a noncorrosive
float button against a smooth contact surface of the exhaust orifice. It shall automatically provide
float button against a smooth contact surface of the exhaust orifice. It shall automatically provide
for the escape of air to atmosphere, without the loss of water,when
the special ball float moves
away from the orifice seat. The float shall be free floating within
the valve body. Linkages of levers attached to the float are not
acceptable.
