Introduction
Generally, there is about 2 vol % of dissolved Air in water. In the process of water delivery, the dissolved air constantly released by water, gathered at the high points in pipeline, it forms "Air pocket" to make water delivery difficult. Therefore, water delivery capacity of water system will fall about 5-15%. The main function of the automatic air valve is to exhaust the 2VOL% of dissolved air.
ARMX series is Cylinder lever type automatic air valve. Small volume, easy to install, with automatic shutdown function, there is no need of water cut-off when maintance. It is commonly used in urban pipeline instrument and hot water heating system, to improve water delivery efficiency of water system and save energy. It is applicable for working pressure "0.02~0.06MPa".
