Product Overview

Operating purpose and application context

Use

The AH42F safety reflux valve is installed in the liquid-phase return line at the pump outlet of an LPG station. When the pressure in the equipment or pipeline exceeds the allowable limit, the valve opens automatically to discharge excess pressure and closes when the pressure falls to the set pressure, helping protect the equipment and pipeline.
