This part of ISO 9635 specifies construction and performance requirements and test methods for 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 irrigation valves of 15 mm diameter or greater, designed to operate in the fully open and fully
closed positions, but which can also operate for extended time periods in any intermediate position.
