Pressure Relief Valves
Pressure relief valves have high flow capacity in order to be capable of efficiently directing flow to tanks. They're used in hydraulic systems, and limit system pressures at specific levels. When a prescribed set pressure limit is reached, a pressure relief valve will immediately respond by sending excess flow from the system back into the tank.
Evergreen Midwest is an authorized dealer of cryogenic pressure relief valves. These work appropriately on piping systems, mini bulk cryogenic containers, and liquid cylinders (alongside ASME relief valves).
- A8560, A8570 and AA8570 Series - Designed as primary relief devices on large stationary pressurized storage containers with flanged openings.
- AR Series - Provide precise control set points to protect cryogenic vessels and piping systems from over-pressurization.
- B-19434B Series/C-19434B Series - B-19434B relief valves are suitable for use with oxygen and non-corrosive gases. C-19434B relief valves are designed for carbon dioxide service.
- DA Series - A complete unitized solution for pressure relief devices assembled in factory settings, ready for attachment to cryogenic bulk tanks. Ideal for OEM applications where pre-fabricated assemblies are favored to streamline construction.
- DR Series - A simple solution for the isolation of pressure relief devices during routine change outs relief valves w/out evacuating vessel. Excellent for protecting bulk liquid vessels, transport trailers, industrial pipelines, and LNG systems.
- NR Series - Designed for indoor applications (such as labs) where relief valve discharge noise is an issue. RegO’s NR series provides excellent flow characteristics with a 50% reduction in outlet noise related to valve relief.
- PRV 9400 Series - Brass or stainless steel, Non-ASME - these relief valves are designed for thermal safety relief applications and cryogenic liquid containers.
- PRV 19430 Series - Brass relief valves/PRV 29430 Series stainless steel relief valves - these are designed for oxygen / other industrial gases and cryogenic service. Apply on piping systems, liquid cylinders, or mini-bulk cryogenic containers where ASME relief valves are needed.
- UA3149A Series - “Pop-type” relief valves especially designed for use as a secondary relief valves in carbon dioxide transports and stationary storage tanks. Designed to protect tanks from excessive pressure in emergency events.
