Introduction of AH42F safety return valve


AH42 type safety return valve

AH42F安全回流阀 产品概述: Product overview of AH42F safety return valve :
适用于液化石油气泵出口的液相出口管路上,用于超压介质的安全回流,标准回流压差大于0.5MPa时液化石油气能自动回流入罐。 AH42F safety return valve is suitable for the liquid phase outlet pipe of the liquefied petroleum gas pump outlet. It is used for the safe return of the overpressure medium. The liquefied petroleum gas can automatically return to the tank when the standard reflux pressure difference is greater than 0.5MPa. The pressure difference of the reflux can be adjusted to 0.3 ~ 0.8MPa, or it can be determined according to user requirements. When the pressure in front of the pump exceeds the specified value, the valve will automatically open and play a role of safe reflux to ensure the safe operation of the equipment and pipeline.
