Cryogenic Pressure Relief Valves

RegO’s NR Series was designed especially for indoor applications (i.e. laboratories) where relief valve discharge noise is an issue. Rego's B-19434 Series are relief valves suitable for use with oxygen and non corrosive gases. The C-19434B Series relief valves are designed for use in carbon dioxide service. 

PRV9400 Series relief valves specifically designed for thermal safety relief applications and for use with cryogenic liquid containers. PRV 19430/29430 Series relief valves are designed for oxygen / other industrial gases and for cryogenic service. Apply on piping systems, liquid cylinders, or mini-bulk cryogenic containers.

The ASME approved 90° relief valves of the AR Series provide precise control set points which protect cryogenic vessels and piping systems for over-pressurization. These valves' configuration provides relief of LNG gases directly, avoiding flow through the spring.
