Sizing of Low Pressure Air Valves for Safe Filling and Draining of Pipelines

Conference paper

Summary

In order to avoid hazardous hydraulic phenomena in water systems, air valves should be included in system design, with carefully calculated orifice sizes.

This paper explains the basic principles of air flow in air valve orifice, and proposes procedures for orifice sizing. It suggests criteria for safe air and water flow velocities, and includes auxiliary tables and examples of sizing calculations.
