SS-RV95
Title:
Cryogenic Relief Valves
RV95 Series

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
