Cryogenic Relief Valves

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.
