All compressed gas cylinders must have safety pressure relief valves. Use the cylinder valve for turning gas off, not the regulator. Never heat a cylinder to raise the pressure of the gas (this can defeat the safety mechanisms built in by the supplier).
These valves can withstand the extreme cold of liquid argon, liquid carbon dioxide, liquid nitrogen, and liquid oxygen. All are cleaned and bagged for oxygen service and other high-purity applications. They automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range.

This type of safety valve is mainly used for the safety discharge system of cryogenic liquid storage and transportation equipment. It has the characteristics of sensitive switching and reliable sealing, and is especially suitable for small volume equipment. Model:DA21Y. Caliber:DN10-40. Cryogenic Relief Valves Rego Pressure Relief ValveThe relief valve is critical in protection against high pressure applications. The Rego Relief valves are applicable in a wide range of applications. Made from brass and stainless steel, the Rego relief valves are designed for thermal safety for cryogenic liquid containers. Every valve
