A42F safety valve installed in the pipeline and storage tank, tank protection, medium pressure in the equipment abnormal elevation to the specified value. Automatic valve opening, and then the whole amount of emissions, play a role in protecting the safety of equipment. For most of the fixed spherical tank. The A42F-16C~40 type is suitable for the water, air, liquefied petroleum gas and the similar non corrosive medium equipment and the pipeline of the working temperature of -40~+80. AH42F type safety valve for liquefied petroleum gas tank pump produced by liquid phase liquid return pipe, when the equipment and pipeline internal pressure exceeds the allowable value, the valve automatically opens, then the whole amount of emissions, when the pressure is reduced to the specified value, the valve automatically closes to ensure the safe operation of equipment.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure,
