Product Description
The refrigerant safety valve is mainly used in the freezing equipment, as the over-pressure protection device of the equipment, when the operating pressure of the equipment increases more than the allowable value, the valve can automatically open, and in accordance with the operating requirements of the equipment, the discharge amount of quantitative medium, in order to prevent the equipment pressure continues to rise, to protect the whole system.When the pressure returns to normal, the valve closes by itself and prevents the medium from remaining.
In order to prevent fire or other abnormal conditions from causing excessive flight system pressure, the refrigerating equipment system must be equipped with a safety discharge valve.It can avoid the refrigeration system at any time to face the overpressure, and automatically shut down after pressure relief, as far as possible to reduce the loss of coolant.
