My "New" Pillar J-valve

[rx7diver]

I posted this pic of my "new" U.S. Divers J-valve (a *pillar* or *post* valve per @Bob DBF; Thanks, Bob!) in another thread earlier today. I purchased this valve from The Scuba Museum earlier this week.

Looks like it's functioning okay; it holds pressure, and the reserve mechanism seems to function fine.

The plan is to use this valve with my U.S. Divers DAAM reg (that has been upgraded with a 1st gen VDH Phoenix nozzle) and either my old-school PST 72 or my OMS/Faber LP66, my VDH Vintage DH plate, and my 23# VDH Argonaut Wing. I'm not sure if I will service the valve first, though.

Any trickiness expected when servicing this particular type of J-valve? I actually serviced my very first J-valve a couple of years ago (Need help disassembling J-valve) with no issues except my own timidness.

Thanks in advance.

A valve is a valve is a valve. I have several of these pillar valves (J and K) on working tanks and they are very easy to service. The only issue I ever had was a leak where air would come out if you pushed down on the J-Rod end cap. After disassembly and reassembly the issue was fixed. Just last summer I had a dive boat here in California refuse to fill my tank because, in the divemaster's words, "Insurance won't let us fill tanks with those old valves because they are known to explode all the time." Really? Ignorant people are not on my most-favored list.

BTW - "thumbs down" is not disagreeing, just indicating "that sucks"....

... "Insurance won't let us fill tanks with those old valves because they are known to explode all the time." ...

I just checked: Mine is the non-exploding type. So, we're okay.

Looks pretty good chrome-wise. Does it have a conventional burst disk?

Mine is a tad crusty but works fine. Takes standard burst discs.

Yes, conventional burst disk.
