标准简介：This part of ISO 9635 specifies construction and performance requirements and test methods for air valves,
intended for operation in irrigation systems with water at temperatures not exceeding 60 °C, which can contain
fertilizers and other chemicals of the types and concentrations used in agriculture.
It is applicable to hydraulically operated air irrigation valves of DN 15 (1/2 inch) diameter or greater,
designed to be directly operated, i.e. the force is applied to the obturator by the float, either directly or via a
mechanical linkage. The valves can be operated by a force applied through an adjustable pilot valve.
