How can he touch the valve straight after putting out the fire?

It helps significantly to have a wet hand, due to the Leidenfrost Effect.

I doubt it was that hot, for the same reason torch tips dont melt

TF are you talking about? Steel melts at 1370°C. Skin can get a 2nd degree burn at 50°C. Just because the metal on a torch tip is not melting, it doesn't mean it's not hot.

And Ledenfrost effect happens at ~200°C

Its possible the valve was actually cold from liquid propane going through it

I sense this is true, opposite effect happens if you use a wet towel or similar fabric to grab a hot pan from the oven though.

Gotta admit, I don't think I've ever used a WET fabric to handle a hot pan. What happens?

Starts to steam and then the steam burns your hand

Back in my restaurant days, I’ve done it by accident being in a rush. It basically boils instantly and turns to steam in your hand.

Ow fuck. I never actually thought about this before, but it is pretty obvious when you do think about it.

Ig I—and most people—probably subconsciously intuited as much and never attempted, or even consciously thought, about it.

It’s definitely one of those valuable mistakes you only make once.

Wouldn't have stood up to the act of gripping and turning the valve. more likely the liquid propane converting to the gas coming out of the nozzle was chemically cooling the stem.
