The valve is suitable for liquefied petroleum gas pump outlet liquid outlet pipeline, for the safe return of overpressure medium, standard reflux pressure greater than 0.5MPa liquefied petroleum gas can automatically back into the tank. May adjust the backflow pressure difference is 0.3~0.8MPa, or according to the user request to determine, when the pump pressure exceeds the specified value, the valve automatically opens, and play a safe return, to ensure the safe operation of the equipment and pipeline.
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.
