標準簡介
This International Standard specifies general requirements and test methods for volumetric valves able to deliver automatically preset quantities of water. It is applicable to valves actuated by pipeline pressure and flow alone, and which do not need any other, external, source of energy.NOTE Volumetric valves are typically required to operate correctly with different qualities of irrigation water at a variety of flow rates and at temperatures of between 5 °C and 60 °C.
