The AHN42 parallel-type safety return valve is installed on the liquid-phase return line at the outlet of LPG storage pumps. When the pump discharge pressure exceeds the preset limit, the valve opens automatically to allow medium recirculation, effectively preventing overpressure and ensuring safe operation of the equipment and piping system. |
