Hi Everyone! Any information is helpful. Used valves are fine. Preferably DIN. I know they're hard to come by, but somebody has to have some. Thanks!

Yes, they are E9791. Thanks for the knowledge!Do you have E9791 3500psi tanks?
If so, those are 7/8" UNF
Thanks for the info, it looks like 7/8 is what I need!As others have noted, early PST HP100s had 7/8" UNF threads, which (confusingly) are smaller than the standard 3/4"-NPSM threads. There are several 7/8" valves on ebay right now, and you can buy new Thermo ones from Leisurepro or Northeast Scuba Supply.
1/2" NPT valves are readily available used in yoke, and new Thermo ones are available in 200 bar DIN, from the same places.
Figure around $80 for a new valve, $40 for used.
Yep, it's 7/8. Thanks!make sure you actually need 1/2" valves. the pst hp100s usually are seen with 7/8 UNF or 3/4 NPS (for the e7 series). a 7/8 UNF valve is only a roughly 5/8 ID iirc as UNF measures by the OD and NPS by the ID. i have only seen 1/2 inch NGT on older low pressure tanks.
