The Flow Control Group supply a complete range of Air Valves for a wide range of applications in the water, wastewater, oil and gas and industrial process sectors.
The specification and selection of a valve and its operating protocols is essential to the optimum performance of any valve. The Flow Control team have the knowledge and expertise to identify the correct valve for the desired application.
Air valves form part of our customized solutions for the pressure control, regulation and surge prevention of pressurized systems.
Air valves are used to both release air from a pipeline and to admit air into a pipeline. Our range includes single, double orifice and combination / triple function air valves.
The function of a small orifice air valve is to allow air to bleed from the pipeline under operating pressure.
Large orifice air valve allow air to be expelled from a pipeline system during filling and to admit air into the system whenever sub-atmospheric pressure occurs
The triple function air valve incorporates a small and large orifice air valve within a single unit. The large orifice functions in two ways, admitting air into the pipeline whenever the system pressure is below atmospheric and expelling air again as the system is refilled or charged. The small orifice allows air to bleed from the pipeline under operating pressure to expel any accumulations of air at high points or charges in pipeline profile.
Our triple function air release valve for sewage guarantees the proper operation of sewage lines allowing the entrance of a large quantity of air in case of pipe burst or draining, the release of air pockets during working conditions and the discharge or air during pipe filling
