Dual Body Combination Air Valve

wastewater

The GA Dual Body Combination Air Valve for wastewater is a two-valve assembly consisting of a wastewater air & vacuum valve and a wastewater air release valve. The combination allows the valve to exhaust large amounts of air at start-up, to release small pockets of air while the system is running, and to prevent critical vacuum conditions during draining. For additional configurations, see Product versions below.

American Iron and Steel compliant version available.
