Product Description

The RegO PRV9434F125 is a brass cryogenic gas pressure relief valve engineered to protect compatible cryogenic gas systems against excessive pressure.

This configuration has a 1/2″ connection, fluorosilicone sealing components, and a factory relief setting of 125 PSIG. The valve is configured with a drain hole and without a pipe-away adapter.

It is specified as O₂ cleaned, making it suitable for appropriately engineered oxygen and other compatible industrial-gas applications where the valve’s materials, pressure setting, and cleanliness requirements are appropriate.

The PRV9430 series is the non-ASME family; avoid describing this particular model as ASME-certified unless the physical valve or accompanying documentation specifically indicates otherwise.
