3/4" High Pressure Cryogenic Valve 2

[jmk0005]

I'm having an extremely hard time locating a valve management has tasked me with finding. I need a 3/4" valve that can handle pressures up to 6,000 psi and operate at -250 degrees Farenheit. The valve is for ground testing and a mimimal amount of leaking is acceptable. Also the fluid is inert gas. Any help or suggestions would be greatly appreciated.

Thanks

The valve exists:

As you will observe: this is a Swiss company. The problem with google search is that any search in English will drown in Asian/China producers, not giving the result you want. Converting your pressure to EN units and inquiry in German language produced the result. (Cryogenic hochdruch ventile PN420).

Have you checked your real necessary flow? A valve with far less flow opwning that normally follows a 3/4" is probably possible, and opens perhaps for valves in other dimensions with separate converting end pieces up to 3/4", perhaps instrument valves.

Best luck!

Consider HiP and Butech. There are others.
