Aira 4matic Global Valve Automation Private Limited

Air valves are hydromechanical devices designed to automatically release air and wastewater gases or admit air during the filling, draining or operation of liquid piping systems for water and wastewater services.

There are many types of air valves installed in potable water supply systems, such as air and vacuum valve, automatic air release valve and combination air valves.

Air and vacuum valves discharge large quantities of air from non-pressurised pipes and are used mainly when filling a line. Air and vacuum valves also make it possible to admit large quantities of air when lines are drained and when the pressure drops suddenly. Air and vacuum valves are also known as: kinetic valves, large orifice air valves, vacuum breakers, low pressure air valves and air relief valves.

Automatic air release valves continuously release relatively small quantities of air from a pressurized line. The automatic air release valve is also known as a small orifice air valve and as a pressure air valve.

Combination air valves fulfil the tasks required of both types of valve - air and vacuum and automatic. They discharge or intake large volumes of air when filling or emptying a system and continuously release small volumes of air when the line is pressurised. Combination air valves are also known as double orifice air valves, double acting or dual orifice.
 

Characteristics of Air Valves:
valves assure that air can be released or admit from a pipeline without water escaping.

These are the advantages of having an air valve in pipeline:

    Reduce Hastened corrosion
    Decreases energy consumption and operation costs
    Accuracy in flow metering
    Reduces the delay time for filling of mains, so increases the efficiency of the pump & pipeline
    Decreases the risk of water hammer
    Sudden movements of air pockets can result in a rapid change in the flow velocity, leading to high pressure surges of a destructive nature. So, by decreasing air pocket in the pipeline reduces the chance of surge

Locations where Air Valves should be installed.
    On rising mains from pumps to release and admit the air
    On long constant-sloped pipeline segments
    At local peaks in the system
    After pressure reductions
    By changes of the pipe diameter
    Along pipeline sections of long uniform slopes every 500 meters
    Street underpasses
    In front of flow meters
    By filter installations

Irrigation has been and is one of the most important occupations in the world, especially with the current modernisation where new and different process are adapted for better cultivation and yield, and how this whole process has changed and developed over years.
