Ball Valves and Gasoline?

[Bryan A.]

Thanks for the info, WOG is the type of info I was looking for.
That first valve is what is on the current setup but I suspect they are leaking air on acceleration. The ball vaves just seem better. They are also cheaper. I will be drawing from two tanks and want to be able to shut off the tanks for reserve and such.

Does anyone know if the G in WOG means gasoline or gas like CO2, argon. etc.
I know I am beating this to death but I just want to be sure before I hook this up. We have enought fuel issues to deal with this year. Price, Ethanol, Iraq, etc.
Thanks guys.

From a Google search:

WOG appears on certain types/models of block or check valves, indicating they are suitable for "water-oil-gas" service, where gas normally means natural gas or propane. The letters "WOG" are always in capital letters and are usually raised—having been cast with the valve body. This abbreviation sometimes appears as "W.O.G.".

Yeah, I saw something along those lines in my searches too. Still the question, to use or not to use .... with gasoline? Is this going to be another component for ethanol to chew on???

valve with WOG on it does not meant it is suitable for gasoline. if it only has teflon/TFE etc than it is fine. if it has elastomer seal such as Viton or Buna, i would not use it. check with apollo.

Apollo literature says the seats and seals, stuffing box ring and seal washer are made of RPTFE. Anyone want to clear up the alphabet soup? I assume the TFE is teflon like edloh stated. What is RP? Rust Proof? Just kidding. They should be fine, yes?
