Air Valve Family

Crispin Air Release, Air & Vacuum and Universal Combination Valves meet or exceed ANSI/AWWA C512 Standards.

AIR & VACUUM SEWER VALVES

The valves have a long body with the float near the bottom. The liquid waste containing solids remains low and away from working parts, venting the pipeline when filling, and permitting air to re-enter to relieve a vacuum. This is a higher capacity variant of the SL (A) Series.
