Generally, there is about 2VOL% dissolved air into the water, which will release out from the water during water transport, and gather on top of pipeline to form air pocket. Because of this, the water transport will become difficult, and the water transport capacity will reduce about 5-15%. And ARVX type micro air valve it’s just applicable to exclude this 2VOL% dissolved air. ARVX type micro air valve is usually mounted in high buildings, pipeline in the factory and small station to protect or improve the system water transport efficiency and energy saving. Single lever micro air valve is oval body, and all the trim are stainless steel, including float ball, lever, seat, while it adopts standard vent hole of 1/6”.
