Type A40Y-16C~40 is suitable for the work temperature are less than 425, A40Y-16I ~ 40I type is suitable for the work temperature are less than 425 of the air, oil gas and other media equipment and pipeline, as the overpressure protection device. When the equipment and internal pressure exceeds the allowable value, the valve automatically opens, then the whole amount of emissions; when the pressure is reduced to the specified value, the valve automatically closes, ensure all the equipment operation.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact.
