Air Release Valve Sizing and Selection - Engineering Guide

The following article by Flomatic Valves discusses the factors to consider when sizing air release valves, including the flow rate of the system, the pressure differential, and the type of valve. It also provides equation for calculating the required valve size. The article concludes by emphasizing the importance of proper sizing of air release valves, as it can help to ensure the long-term reliability and efficiency of piping systems.

• Air release valves are typically sized based on the flow rate of the system and the pressure differential across the valve.
• The American Water Works Association (AWWA) has published standards for sizing air release valves.
• There are three main types of air release valves: air/vacuum valves, air release valves, and combination air valves.
• The type of air release valve that is used will affect the sizing calculations.
• Properly sized air release valves can help to prevent air pockets from forming, which can improve the efficiency of the piping system and prevent damage to the system.
