The GA Single Body Combination Air Valve is a
two-valve assembly consisting of an air & vacuum valve and an 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. The
Kinetic feature prevents the valve from blowing shut before all the air
is vented. For additional configurations, see Product versions below.
American Iron and Steel compliant version available.
