A47 spring slightly open safety valve is applicable to equipment and pipelines with water, air and other non corrosive media ≤300°C. When the medium pressure reaches the specified opening pressure, the valve automatically opens (the opening height is not less than 1/20do), and then discharges in full. When the pressure drops to the specified reseating pressure, the valve automatically closes to ensure the safe operation of equipment and pipelines.
