Air relief valve for clean water and neutral liquids to max., 70°C. Used for applications like water distribution systems, irrigation, building and pump cases.
AVK Air release valve automatically releases air pockets accumulated on critical points of the pipeline such as high point and changes in slope avoiding unwanted head loss and reduction in flow through the system. Thanks to the lever mechanism, the float force is multiplied to reach low sealing pressure values. The valve ensure high accuracy also in low flow rate conditions thereby drasticaly reducing the maintenance operations.
