The SANA42F internal safety valve is mainly used on railway and automotive liquefied gas tankers or ground liquefied gas storage tanks, providing overpressure safety protection. The scope of use is very extensive, and the same valve has different combinations in different occasions and working conditions

 

Working principle of built-in safety valve

 

The safety valve plays a safety protection role in the system. When the system pressure exceeds the specified value, the safety valve opens to discharge a portion of the gas in the system into the atmosphere, ensuring that the system pressure does not exceed the allowable value, thereby ensuring that accidents do not occur due to excessive pressure.
