Air Valve Family

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


Available in both potable and wastewater configurations, the VR and SVR Valves allow air to enter a system when a negative pressure occurs, but prevents air from being released under positive conditions, except through an optional small orifice Air Release Valve.
