Product Description

The RegO PRV9432T450 is a compact brass cryogenic gas pressure relief valve designed to protect cryogenic gas systems from excessive pressure.

This configuration features a 1/4″ connection, PTFE sealing components, and a factory-set relief pressure of 450 PSIG. The PTFE configuration is particularly suited to extremely low-temperature cryogenic gas applications.

The PRV9432T450 has a drain hole and does not include a pipe-away adapter. It is also specified as O₂ cleaned, making it suitable for properly engineered oxygen and compatible industrial-gas applications when all system and installation requirements are met.

The PRV9430 family is RegO’s non-ASME cryogenic relief-valve series. Therefore, this model should not be advertised as ASME certified unless the physical valve or accompanying certification specifically states otherwise.

Typical Applications

• Cryogenic liquid cylinders
• Cryogenic vapor-space protection
• Oxygen systems
• Nitrogen systems
• Argon systems
• Industrial gas equipment
• Cryogenic piping systems
