Air release and air/vacuum valves are used to manage air in water and wastewater systems. Air release valves help remove small air pockets that can form in pressurized pipelines, protecting against water hammer, and they come in different sizes and materials for various applications. Air/vacuum valves can handle large amounts of air during filling or draining, work automatically with a float mechanism, and protect against vacuum damage, helping to keep pipelines efficient and safe.
When selecting these valves, it's important to know if you need them for releasing air or for allowing large amounts of air into the system during filling or draining. You should also think about the size of the valve, the materials it is made from, where it will be installed, and how easy it will be to maintain.
