On the refrigerant safety valve's main user freezing equipment, it is used as the overpressure protection device of the equipment. When the operating pressure of the equipment increases beyond the allowable value, the valve can be opened automatically, and according to the operating requirements of the equipment, the medium with a fixed discharge amount can be used to prevent the pressure of the equipment from rising further and protect the whole system. When the pressure returns to normal, the valve closes itself and prevents the medium from flowing out.
Safety relief valves must be installed in the refrigeration system to prevent fire or other abnormal conditions from causing excessive pressure on the system. It can avoid the overpressure the refrigeration system faces at any time, and automatically shut down after the pressure relief, minimizing the loss of coolant.
