Bibliography

Describes construction and performance requirements and test methods for control valves, intended for operation in irrigation systems with water at temperatures not exceeding 60 degrees C, which can contain fertilizers and other chemicals of the types and concentrations used in agriculture.

This part of ISO9635 specifies construction and performance requirements and test methods for control 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 control irrigation valves of DN15 (1/2inch) diameter or greater, designed to operate in any position, from fully open to fully closed. The valves can either be directly operated (i.e. the force applied via a spring or diaphragm to the obturator), or pilot-operated (i.e. the force is applied through an adjustable pilot valve via a diaphragm). These valves can also function as check valves.
