Cryogenic Relief Valves
RegO’s NR Series is designed especially for indoor applications (i.e. laboratories) where relief valve discharge noise is an issue. PRVs provide excellent flow characteristics with a 50% reduction in outlet noise related to valve relief.
• Packaged and cleaned for oxygen service per CGA G-4.1
• Bubble tight at 95% of set pressure
• 100% factory tested
• Repeatable performance
• Temperature range -320° to +165° F
The B-19434B Series relief valves are suitable for use with oxygen and non corrosive gases. The C-19434B series relief valves are designed for use in carbon dioxide service.
• Both designs permit the valve to open slightly to relieve moderately excessive pressure.
• When the pressure increases beyond a predetermined point, the valve opens to its full discharge capacity in order to quickly reduce excess pressure.
• Pipe-away adapter for venting gas to the outdoors is available.
• A.S.M.E. rated. NB Certified.
• B-19434-B Series are cleaned for use in oxygen per CGA G-4.1.
UA3149A Series
“Pop-type” relief valves are designed for use as secondary relief valves in carbon dioxide transports & stationary storage tanks. The relief valves are designed to protect tanks from excessive pressure in event of fire /other emergencies. Small throttling-type primary relief valves must be provided to control boil-off and maintain tank pressures. Provisions must be made to prevent accumulation and build-up of water and foreign material in valves.
- “Pop-type” design permits relief valve to open slightly to relieve moderately excessive pressures.
- Relief valve “pops” open to full discharge capacity when pressure exceeds a predetermined point.
- 100% Factory Tested
PRV 9400 Series
These relief valves are specifically designed for thermal safety relief applications and for use with cryogenic liquid containers.
- All valves are cleaned and packaged for oxygen service per CGA G-4.1.
- Bubble tight at 95% of set pressure.
- Easy to read color coded psig / bar labels.
- Adapters provide standard pipe thread connections for venting gas to the outdoors.
- Repeatable performance.
- 100% factory tested.
- Temperatures Range -320° to +165° F.
PRV 19430/29430 Series
These relief valves are designed for oxygen / other industrial gases and for cryogenic service. Apply on piping systems, liquid cylinders, or mini-bulk cryogenic containers where an ASME relief valve is desired.
• A.S.M.E. rated, National Board Certified.
• Bubble tight at 95% of set pressure.
• Full flow at 110% at set pressure.
• Repeatable performance.
• 100% factory tested.
• Temperatures Range -320° F to 165° F.
• Cleaned and packaged for oxygen service per CGA G-4.1.
