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.
