Brass valve, but for what?

[johnreb1980]

I founds this brass valve the other day while searching for Civil War relics and was wondering what it might have went to? I believe it has been in the ground for awhile due to the nice thick green patina it has on it. Any help would be greatly appreciated on it. Jonathon

I seen some on a steam powered fire department water pumper from the 1800's in a museum last year. I think your valve is from the 1800's to the turn of the century off some type of steam boiler. I have found 10 or so different types of them metal detecting. The reason that I think that it's an old one is the design of the turn off on it. I have an old spigot that was used in beer barrels that has the same design turn off valve on it.

close but no cigar yet. im thinking its a l.p. or natural gas petcock for a gasslight or fireplace.

I'm thinking petcock to drain radiator, there is no attachment on the other end for gaslight or LP. Just my guess. HH

model T's used a similar petcock for draining the block...

I am thinking natural gas valve. Rubber hose fits over the "nub" on the out side of the valve and a hose clamp seals it. Use to be common to hook up natural gas heating stoves up through the 1950s. Dad had such a valve in the first house I remember as a child. Grandad had one in his bedroom as the back of his house had no heat and he ran gas back there through a rubber gas line. They were outlawed by codes in the 1960s. Monty



Here are some similar although not identical.

By George, I think Mojjax has it! Identical one on top of that what ever it is! Looks like it may bleed of pressure or something? My average is now about .043% and falling! But I sure like guessing. Monty

Good pics mojjax. Mark this one Solved please.

Mojax gets the star for the great research on that one!

It could have been used for any number of applications, as Monty said.
Gasline, draining off condensate in a heating radiator, bleeding off a still...

I thought it was interesting that it seems to have a left hand thread on it.
That could indicate it's for a gas application.

What a great resource, here at Tnet!
