Credit: 1 PDH
Subject Matter Expert: A. Bhatia, Mechanical Engineer
In Selection and Sizing of Air Release Valves, you'll learn ...
- The four primary ways that air gets introduced into a liquid pipeline
- The problems and dangers attributed to the presence of air in pressurized pipelines
- The various types of air and vacuum release valves
- Air/vacuum valve sizing criteria
Overview
To meet the Ohio Board's intent that online courses be "paced" by the provider, a timer will be used to record your study time. You will be unable to access the quiz until the required study time of 50 minutes has been met.

Air valves are used for the release of air pockets in water lines. When air is allowed to accumulate in pressurized pipelines, efficiency is sacrificed and serious damage can occur. An air valve is designed to allow the automatic discharge of large amounts of air from the water main, while it is being filled, and also to allow air to enter the water main, when the water line is being emptied. It will also allow the air to escape the water main when it is in operation and under pressure.
If air valves are not installed, uncontrolled air releases may occur, causing pressure surges in the system potential damage due to cavitation.
This 1-hour course will describe the basic theory of air valves; explain their operation, and provide methods and tools to specify, locate, and size air valves for maximum flow efficiency and surge protection.
