Series AT503 is designed for automatically reduce the pressure to a lower “pre-set pressure” and constant flow regardless of fluctuations of inlet pressure as long as the supply pressure does not drop to the below pre-set pressure. We recommend to install a self-cleaning Filter or Y-strainer upstream before the Pressure Reducing Valve in case of dirty fluids. It can be installed in horizontal or vertical positions in the pipeline system. ● Brass direct acting type ● Maximum inlet pressure 25bar ● Adjustable outlet 1 to 6bar ● Maximum temperature 80°C ● Application: Air, Oil, Water, Hot cold water, Non-corrosive fluids, Fluids compatible to “material of construction”
