ARVX MICRO EXHAUST VALVE, UNDER NORMAL CIRCUMSTANCES, THE WATER CONTAINS ABOUT 2VOL% OF DISSOLVED AIR, AND DURING THE WATER SLEEP, THIS AIR IS CONTINUOUSLY RELEASED FROM THE WATER AND COLLECTS AT THE HIGH POINT OF THE PIPELINE, FORMING AN AIR POCKET. This makes water transport difficult, and the system's water delivery capacity can be reduced by about 5-15%. The main function of this micro exhaust valve is to remove this 2VOL% dissolved air, and is suitable for installations and high-rise buildings, factory piping, small pumping stations to protect or improve the water transmission efficiency of the system and save energy.
