AWWA Air Release Valve

SVR Global is a reliable AWWA Air Release Valve Manufacturer and Supplier in USA and Canada, providing valves designed to maintain pipeline efficiency by automatically releasing trapped air and admitting air when required. Manufactured in compliance with AWWA C512, our air valves protect pipelines, pumps, and water distribution systems from air-related problems such as flow restrictions, water hammer, and pressure surges.

Standards We Comply With

• AWWA C512 – Air release, air/vacuum, and combination air valves for waterworks service

Types of AWWA Air Valves Offered by SVR Global

• Air Release Valves

• Air/Vacuum Valves

• Combination Air Valves

Function & Working

Air valves are installed at high points in pressurized pipelines where air tends to accumulate. Air release valves discharge small air pockets during operation. Air/vacuum valves release large volumes of air during filling and admit air during draining. Combination valves perform both functions in one body, ensuring complete air control throughout all operating conditions.
