Under normal circumstances, the ARVX micro exhaust valve contains about 2VOL% dissolved air in water. During the water delivery process, this air is continuously released from the water and accumulates at the high points of the pipeline, forming an air bag, making water delivery difficult. As a result, the system's water delivery capacity can be reduced by about 5-15%. The main function of this micro exhaust valve is to remove the 2 VOL% dissolved air, and it is suitable for installation in high-rise buildings, factory piping, and small pump stations to protect or improve the water delivery efficiency of the system and save energy.
