The AHN42F parallel safety return valve is suitable for use on the liquid phase return line at the outlet of liquefied petroleum gas tank pumps operating at temperatures between -29°C and 80°C. It is designed for the safe return of overpressurized media.
Working Principle
When the standard return pressure difference is more than 0.5MPa, the liquefied petroleum gas can be automatically returned to the tank.AHN42F parallel liquid-phase safety return valve can be adjusted to the return pressure difference of 0.3~0.8MPa, or according to the requirements of the user to determine, when the pressure in front of the pump exceeds the specified value, the valve automatically opens and plays a role in the safety of the return to ensure the safety of the operation of the equipment and pipeline.
