Series

RegO 9400 Series – Non-ASME Cryogenic Gas Relief Valve

Product Description

The RegO PRV9434F100 is a compact 1/2″ brass cryogenic gas pressure relief valve designed to protect gas and cryogenic systems against excessive pressure. It is factory set at 100 PSIG and incorporates a fluorosilicone seat/softgoods.

This configuration has an integral drain hole and is supplied without a pipe-away adapter. The valve is O2 cleaned, making it appropriate for oxygen-service systems when installed in accordance with applicable codes and equipment requirements.

The PRV9434F100 belongs to RegO’s 9400 Series of cryogenic gas relief valves, commonly used for vapor-line pressure protection on cryogenic liquid containers and related industrial gas equipment.

Fluorosilicone Seat

The fluorosilicone seat provides good sealing performance and resistance to many industrial gases. For eBay, I would not advertise this version as having the -320°F temperature rating associated with PTFE-seat variants. The fluorosilicone configuration generally has a higher minimum operating temperature.

Typical Applications

  • Cryogenic liquid-cylinder vapor spaces
  • Industrial gas equipment
  • Oxygen systems
  • Nitrogen systems
  • Argon systems
  • CO₂ gas equipment where specifications are compatible
