Double Orifice Air Release Valve , SS316 DN 200 PN16 Automatic Air Release Valve

Double Orifice And Integrated Valve SS316 DN 200 PN16 Automatic Air Valves

Quick Details

The double orifice automatic air valves with integrated valve are used for applications related to troubles

with air in the pipelines. The double air valves with integrated valve working as isolating valve allow maintenance

or replacement of balls in line.
The minimum pressure on seat is 0,3 bar.

The double ball air valves have three functions:

• Discharge large amount of air during filling operations

• Discharge small amount of air during working operations

• Let air in during piping emptying operations

Working conditions:

Treated water max. 70°C;Designed in compliance with EN-1074/4.

Max. 40 bar;Standard connection 1", flanged on request. Flanges according to EN 1092/2.

Min. 0.1bar. Epoxy painting applies through fluidized bed technology blue RAL 5005.

Changes and variations on the flanges and painting details available on request.

Air valves:

Air valves in pipeline systems serve two primary functions.

1.The first is the release of accumulated air that comes out of solution within a pressurized pipeline. This air will

result in bubble formation, which will gather at localized high points along the pipeline profile. This air accumulation will

occur when the bubble’s buoyancy is greater than the energy to convey the bubble with the liquid.

Air valve used to release this free air is known as an air release valve.

2.The second function of an air valve is to admit air into the system when the internal pressure of the pipeline

drops below atmospheric pressures. By admitting air into the pipeline as the internal vacuum condition develops,

the magnitude of the vacuum pressure can be reduced and as a result help prevent the pipeline from experiencing excessive

deflection and/or collapse as well as help prevent the formation of a full vacuum condition in which vapor cavities may form

the fluid vaporizing.

Air valves can contribute to the improvement of the efficiency of the water system.
