Air valves are a unique design (embodying Aerokinetic principle) of air relief valves for water systems. Air valves have capacities greater than those of other conventional air relief valves. Top performance and high durability are the characteristic of all the different types of air valves in the range :- Single Orifice Air Valve (Single Acting) - for automatically releasing air accumulating in pipelines during normal working conditions to prevent interferences with pipe flow capacity.

Double Orifice Air Valve (Double Acting) - include the functions as Single Orifice Air Valve as well as for automatically exhausting air from a pipeline when it is being filled with water, the air being released at a sufficiently high rate to prevent back pressure restriction of inflow rate; or for automatically ventilating a pipeline when it is being emptied of water, the air inflow rate being sufficiently high to prevent the developtment of high vacuum pressures in the line.
