The ARV-A automatic double-acting air valve is designed to effectively expel air accumulated in pipes, filters, tanks and any place where the presence of air is detrimental to proper operation. Air valves are located at the outlet of pipes whose slope varies in relation to the hydraulic gradient, at points where the pipe rises above ground level, in large branches with a uniform slope, at the inlet of measuring instruments, at the outlet of reducing valves, in diameter reductions, pumps, filtering systems and on each side of crossings under roads. For proper operation of the valve, it must always be placed in a vertical position. It is recommended to install a manual isolation valve under the air valve, in order to allow maintenance and repair operations without having to shut down the entire system.<\/p>\n
