Arvx trace exhaust valve in the general case, the water contains about 2VOL% of dissolved air, in the main water course, the air continuously released from the water, gathered at the high point of pipeline, formation of air bags (air pocket), so that water becomes difficult, the transportation capacity of the system can be so about 5-15% decline. The main function of micro exhaust valve is excluded of this 2VOL% of dissolved air, and suitable for installation in high-rise buildings, plant area piping, small pumping stations used to protect or improve the system of water efficiency and save energy.Features:
