The propane tank for my forge (and oxy/propane torch) is the newer style with a float type safety valve. Yesterday while trying to test a new burner it was soon found that nothing was coming out of the tank. When everything was disconnected I discovered that it was heavy and just to confirm it, the farm coop couldn't get it to take anything either. Is there a way to make this thing work temporarily until it can be exchanged for another one? Anything like this ever happen to anyone else here? Kevin B

Hey Kevin:
Yep, I've been there... Went out one day to shoe a bunch of horses... Took a little propane cylinder and couldn't get anything to come out of it... Got the horseshoes forged with the aid of the client's cylinder off their barbeque. Brought the tank home and dropped it on it's head a couple times... Fixed it! :skip:

I found if I didn't use the quick connect knob and used an older style that needed a wrench my problems went away. I'm not sure if this was just a fluke or not but it did work for me. The new tanks are designed to limit overfilling so they won't vent into a vehicle while being transported in a hot car/trunk. Hope this helps.

WARNING: The new tanks WILL vent if over heated, such as when transported in a hot car or trunk. The tanks are designed to vent vs. rupturing.

Thanks much guys for the info! Bumped it around yesterday without much success and today was prepared to give it a little rougher treatment but it suddenly just worked. I'm not sure, but suspect that this same thing is what has been causing flames to go oxidizing. Constant readjustment and blaming old regulators all the time. I'd rather just avoid that "safety valve" altogether but with my budget will probably opt, temporarily at least, for an exchange of the same and hope for a better valve. Again thank you. Kevin

I think some of the newer cylinders may have valves designed to shut down if propane is withdrawn too fast (for example if the hose gets cut). I know that some of the Acme-thread regulators have that feature -- the one I use does.
When I open the tank valve, it takes maybe 30 seconds for the system to come up to pressure, after which I hear a little click. As long as I wait until then to open the valve on my forge, everything's fine; otherwise, the safety valve shuts down, and I have to close the forge valve and wait for the pressure to come up again. Actually, I occasionally have the same problem if the regulator's cranked up pretty high and I open the forge valve too quickly. The cure is the same.
Don't know if your problem is along these lines, but might be something to check.

Thanks Mike B
that is what I remember happening to me, I just didn't recognize the corelation. I know the new valves were mandated as a safety feature. That must be why my 100lb tanks never gave me problems... no quick connect/acme thread attachment.
