AH42F lpg safety back-flow safety adjustable pressure relief valve
Pressure safety relief valve is used in liquefied petroleum gas liquid phase exit pipe with working temperature of -40 to 80℃. When inlet and outlet pressure difference is larger than 0.5MPa, the liquefied petroleum gas will back flow to tank automatically.
A42F-type safety valve applies to equipment or pipelines with LPG or similar non-corrosive media whose operating temperature is -40 to 80 ;
AH42F type safety valve applies to LPG tank pump station outlet liquid reflux pipeline. When the pressure inside the tubes of equipment exceed allowable value, the valve automatically opens, and then comes full emissions, when the pressure decreases to the required value, the valves are automatically closed to ensure safe operation of equipment.
