Duplex safety valve safety valve, steam valve is suitable for the work temperature are less than 350, the equipment and piping of air medium, when the equipment and pipeline internal pressure exceeds the limit from the noise, the valve automatically opens, then the whole amount of emissions, when the pressure is reduced to the specified value, the valve automatically closes to ensure the safe operation of equipment and piping.
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.
The valve is installed in a Y type of the same model of the safety valve, based on the nominal diameter is the Y connector inlet diameter, the combination of the following:
