Purpse of air exhaust valves

Air can enter water pipes from a variety of sources like pipe leaks, fluid level changes and temperature fluctuations. If not released, this trapped air can cause problems like water hammer, ineffective flow and issues with pump operation. An air exhaust valve releases this trapped air to the atmosphere, keeping the pipe system functional.

Design of waterworks air exhaust valve

Waterworks air exhaust valves typically have a float that rises with accumulating air and opens a valve orifice to allow the air to escape. Once the air is released, the float lowers and closes the orifice.

Materials of air exhaust valves by Fluid Tech Group

Air exhaust valves for waterworks are made of corrosion resistant materials suitable for contact with potable water. Common materials include bronze, ductile iron, stainless steel.

Installation of valves as air exhaust type

Valves as air exhaust type are installed at high points along water pipelines to capture any trapped air pockets. They are typically installed vertically with the orifice facing upwards. Multiple valves may be needed depending on the pipe layout and elevation changes.
