PRV19434T250

Product Description

The RegO PRV19434T250 is a heavy-duty ASME-rated cryogenic gas pressure relief valve designed for oxygen and other industrial-gas systems. It features a 1/2″ NPT inlet, durable brass body, stainless-steel spring trim, and PTFE softgoods/seat.

The valve is factory set to relieve at 250 PSIG and incorporates a drain hole. This configuration is supplied without a pipe-away adapter. RegO specifies the 19430 Series for cryogenic vapor-space service on piping systems, liquid cylinders, and mini-bulk cryogenic containers.

The valve is cleaned and packaged for oxygen service per CGA G-4.1, making it appropriate for systems where oxygen cleanliness is required.
