Scope
This standard specifies the technical requirements and test methods for quantitative valves. The quantitative valve can calculate the amount of water flowing through it at various flow rates when the water temperature does not exceed 50 °C, and it can automatically shut off when the preset irrigation water volume is reached.
This standard applies to quantitative valves that are driven solely by pressurized water flow in the pipeline and do not require any other external energy sources.
