Working Principles
Plastic air discharge valve operates in 2 modes.
1-evacuation mode: with the flow of water in the system in some way, the air pipe fills a large amount of the system. When the water reaches the air discharge valve, the valve flat moves up and prevents the water from coming out of the system and removes the air from the system.
2-system pressure balancing mode: after emptying the air in the system, the system balances the difference between the pressure and atmospheric pressure.
