Anyone know these fittings?

[kneisska]

I'm not sure what these are. Anyone have any idea? I don't know if they are gas or water fittings or what. This is not my fortay. Any help would be appreciated. Thanks!

could it be a propane valve for two tanks when one tank runs out you turn to the other tank and vica=versa just a guess, bob w.

Any importance to the writing there that you can't really see in the 2nd picture? Reminds me of the valves we used for co2 tanks (like bob said), when one of the tanks went low we had to switch it to the other side.

From the first and last pictures, as the handle is aligned with the compression fittings - it looks like flow is allowed from one compression fitting to the other; but not from the one threaded side to the other.

I'd guess, turning the handle /valve 90 degrees will do the opposite.

Could this be a control valve to switch a bi-fueled device?
