AIR VALVESAIR VALVESDESCRIPTION and TECHNICAL DATAAir VALVES General:What is an air valve ?An air valve is a valve mounted in TEE configuration on a pipeline to discharge or admit air into or out of the pipeline. Why should the air in the pipeline to be controlled? The existence of trapped air in a pipeline under pressure can cause negative effects on system operation and pockets accumulating at slope sign changing high points reduce the effective cross-section of the pipeline in the location of accumulation, which causes a decrease in the flow rate, and the energy needed to pressurize the waterflow is overall system efficiency is then reduced. Air pockets beyond some critical quantity in the system even may restrict the whole pipeline from flowing, locking the of Air in Water Pipelines The existence of air in a pipeline might be because: Air under atmospheric conditions might stay within thepipeline when the pipeline was filled with water.
