Aquabrake Double Orifice Air Valve

Aquabrake® double orifice air valve is an innovative combination of small and large orifice air valve within one compact cylindrical housing.  The function of the large orifice is to admit bulk air during the pipeline draining phase and expel bulk air during system filling.  Under operating conditions, any small accumulations of air are bleed through the small orifice. The novel design features corrosion restraint components acting through a central axis and reduced weight when compared to comparative units. 

Used to prevent pressure build-up, vacuum in the pipe system and to control bleed of gas to maintain stability. Suitable for potable and filtered water applications.  Please see below our Working with Air Valves document and the Aquabrake Double Orifice datasheets under the Technical Features tab.

Orders placed by 3-30 pm have same working day dispatch and prompt delivery, normally next working day delivery, on selected models only.

Currently we are experiencing issues in achieving next working day delivery in some areas due to HGV driver shortages.
