Product Details

Product Overview
The fully open safety valve with a radiator is suitable for equipment and pipelines with working temperatures ≤ 425 ℃, and A40Y-16I-40I models are suitable for air, petroleum gas, and other media with working temperatures ≤ 425 ℃, as an overpressure protection device. When the pressure inside the equipment and passenger roads exceeds the allowable value, the valve automatically opens and then fully discharges; When the pressure drops to the specified value, the valve automatically closes to ensure the equipment operates at full speed.
