Cryogenic Relief Valves
This safety valve is specifically designed for cryogenic gases, and can be used for pipeline systems, cryogenic
cylinders, or small cryogenic tanks. When the pressure in the system surpasses the preset pressure value, the
valve will automatically start relieving excess pressure.
Features
• Valve opens on preset value and reseats below 95%
• Operating Temperature: -321 ~ 165ºF (-196 ~ 74ºC)
• Available Set Pressure: 22 ~ 500 psi (1.5 ~ 34.5 bar)
• Conforms to CGA G-4.1 for cleaning components
• Constructed with oxygen compatible materials

Excess Flow Valves
Used in cryogenic liquid cylinders or piping systems to prevent
uncontrolled release of cryogenic fluid in the event of a rupture or
abnormal excess of flow downstream of the pipeline.
Features
• Maximum working pressure: 580 psi (40 bar)
• Working temperature: -320~176oF (-196~80oC)
• Cleaned for oxygen service per CGA 4.1, suitable for use under pure oxygen environment

Burst-Disc
The Burst Disc is designed for use with cryogenic storage vessels
with insulation, piping, or other confined spaces to prevent
over-pressurization. It is often used as part of a pressure relief
system. When used with a pressure relief valve, it acts as an emergency
option to relief excess pressure. In the event the relief valve fails to
open, the burst disc shall rupture to release excess pressure.
Features
- Suitable for gas, liquid two kinds of medium and high pressure
conditions of blasting
- Working temperature：-320~158 oF (-196~70 oC)
- The burst pressure of the maximum working pressure up to 80%
