    Air Release 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.

    Air Release Valve Feature

      1. Large Air Exhausting when pipe systems are filling
      2. Air venting of small bubbles ( 2% of solved air in water) after the mean float closed
      3. Air intake during the vacuum of Pipes .
    • Range DN50-80-100-150-200 full bore size.
