Strange Pro Valve

[sdavo]

I didn't like the depth of them. Deeper than a 200 bar DIN, not as deep as a 300 bar DIN, they used every thread you had on a 200 bar regulator, and so the DIN nut would bottom out. You'll see them on the white painted Faber cylinders. Which is what I think your picture shows, doesn't it?

Yeah, it's a white painted Faber. It turned out to be one of the DOT-E 80 cu. ft. "lightweight" cylinders with terrible buoyancy characteristics. Not my finest Craigslist purchase, for sure.

Well, put it back on Craigslist. Or eBay.

Anybody seen a pro valve that doesn't have the yoke clearance chamfers cut into the back like this one? It came on a used tank I bought. My LDS checked the part number on the valve and said it should have been a standard pro valve. The valve in the tank is the new one I bought to replace the one we couldn't get a yoke over.

SD...

I had one of these...

300 BAR...never intended to have a yoke plug...DIN only...threaded too deep for a yoke plug to work...

Looks like your sample is severely ''out of round''...yoke plug appears to be either jammed in because the female valve thread is damaged or ''packed in'' from behind...in either case it will leak severely...

This valve will also not have the yoke bolt dimple in the back unless that was added as well...

What you're showing is now scrap...valve and yoke plug...

Hope this helps...
