Air Valves

Netafim offers Air and Vacuum Air Valves, Combination Air Valves and Automatic Air Valves in multiple sizes and body materials.


Why Use Air Valves?

The lack of control over the air present in a fluid system can result in damage such as destructive vacuum conditions, high pressure surges, inaccuracies in the measurement of fluid flow and it can have a detrimental effect on the efficiency of system drainage. Entrapped air exists in all fluid transmission systems. The principal sources for this are:

  • Incomplete filling of the line – which leaves air pockets in high places and in different accessories.
  • Air dissolved in the fluid, released when the pressure drops and/or there is a rise in temperature.
  • Vortices and turbulence, which introduces air into the system at the points from where it is pumped.
  • Air is sucked into the system through cracks and gaps in pipe accessories, fittings, seals, etc.
