JPotts: With these newer propane tanks that have the OPD valve( overflow protection device), if they are opened to quickly, allowing a lot of propane to flow out quickly, the built in safety device will stop or slow the flow of propane. Whenever opening these valves, it should be done slowly. First , just crack it, then slowly open it to the full position. I was at a cookout and the host couldn't figure out why his grill wasn't coming up to temperature after changing the tank. I shut the valve, waited a minute, then cracked it then opened slowly. Back in business!! Hope this helps!
