Surge-Suppression Air Valves, AWWA C512, WQA Certified Lead-Free, Val-Matic® Valve

Surge-Suppression Air Valves, AWWA C512, WQA Certified Lead-Free, Val-Matic® Valve


Surge-Suppression Air Valves are Combination Air Valves equipped with Regulated-Exhaust Devices (slow-closing devices) to limit secondary surges during column separation. The Val-Matic® Surge-Suppression Air Valve provides full airflow into the pipeline during vacuum conditions to prevent a vapor pocket (vacuum) from forming.
