Application Summary AI generated
GB/T 21386-2008 specifies the design, performance requirements, and test methods for ratio pressure reducing valves, which maintain a constant outlet-to-inlet pressure ratio regardless of flow variations. It is applied in fluid systems such as water supply, fire protection, and industrial piping networks where precise pressure reduction is critical for system safety and equipment protection. The standard is used by manufacturers, engineers, and quality inspectors to ensure consistent valve behavior in hydraulic and pneumatic applications.
