Product Description

The AHN42F parallel-type safety reflux valve is designed for use on the liquid-phase reflux line at the outlet of a LPG tank pump operating at temperatures ranging from -29 to 80 ℃, and is intended for the safe reflux of overpressurized media.

How It Works

When the standard reflux pressure differential exceeds 0.5 MPa, liquefied petroleum gas can automatically reflux back into the tank. The AHN42F parallel-type liquid-phase safety reflux valve allows the reflux pressure differential to be adjusted between 0.3 and 0.8 MPa, or as specified by the user. When the pressure upstream of the pump exceeds the specified value, the valve automatically opens to provide a safety reflux function, ensuring the safe operation of the equipment and piping.
