Scope
This document specifies the structure, technical requirements, and test methods for linear-acting pressure regulators (hereinafter referred to as pressure regulators). These pressure regulators are used in agricultural irrigation systems that contain water with a temperature not exceeding 60°C, and the water may contain fertilizers and other chemical substances commonly used in agricultural irrigation at standard concentrations.
This document applies to pressure regulators with a nominal diameter not exceeding 100 mm.
