Application Summary AI generated
GB/T 28778-2012 specifies the design, performance, and testing requirements for pilot-operated safety valves used in fluid systems. It applies to industrial applications such as petrochemical, power generation, and gas processing where precise overpressure protection is needed. The standard ensures these valves reliably control pressure by using a pilot mechanism to actuate the main valve, reducing leakage and improving response in high-pressure or high-flow scenarios.
