Air Valve Selection & Installation: Combination of air & water is very dangerous for PVC Pipes. Air Being compressible in nature, tends to accumulate in the pipeline and in case of non-functioning of air valves it results in high localized pressure. To avoid this phenomenon, good quality air valves should be installed at all peak points in the pipeline with a distance of 300 to 400 meters between them. Air Valves are of two types: Single Acting & Double Acting. It is recommended that the size of air valve should be about 1 /4th the diameter of pipe for the admission as well as release of air. The function of an air valve is the same as that of a nose in a human body.
