Advantages: Increases the system equipment life and save the water in tank which is used for unnecessary operations. These valves are used to reduce the pressure which is over the limits on the system. After hydraulic calculations, users obtain the design pressure, after that users do same hydraulic calculations for the other areas. In this areas fire pump are selected according to the highest pressure. For this pressure adjustments pressure reducing valves are used. Users have use manometer with these valves in front and back. By the output of the valve pressure reducer ½ ” provided that it is not smaller than the relief valve should be used. May not exceed 12.1 bar relief valve setting pressure.
