Important Installation Information

Pressure relief valves are critical safety components. The replacement valve must have the correct pressure setting, connection size, flow capacity, materials, and certification for the specific vessel or system.

Installation should be performed by qualified personnel in accordance with RegO instructions and all applicable ASME, CGA, local, and facility requirements. Do not change or adjust the factory pressure setting unless specifically permitted by the manufacturer.
