Vacuum jacketed cryogenic valves are used with a variety of different cryogenic liquids for control and transfer in:
- Vacuum Jacketed Piping Systems
- Cryogenic Equipment Drops before the use point
- Bulk Tank Shutoffs
- Capped bayonets to allow system expansion without shutdown
Safety Relief Valves are mounted a minimum of 5” (13 cm) away from the main transfer line to reduce heat conduction.
To prevent icing of the valve insulating non-vacuum jacketed
SRVs is not recommended. Relief valve sizing should be determined based on Compressed Gas Association (CGA) guidelines.
Although Safety Relief Valves do not vent or relieve in normal
system operation, proper venting must be considered since gas or even liquid can be expelled when high pressures are encountered.
Please consult a Technifab representative to determine the correct sizing and locations of Safety Relief Valves for your system.
