Scope
This document specifies the technical requirements and test methods for quantitative valves capable of automatically delivering a preset amount of water.
This document is applicable to quantitative valves that are driven solely by pressurized water flow within the pipeline and do not require any other external energy sources.
Note: It is generally required that quantitative valves can operate normally under various flow conditions and with different quality of irrigation water at temperatures ranging from 5 ℃ to 50 ℃.
