Help identifying this 1/2 inch true union valve

[Areseebee]

Might be a longshot, but i'm trying to match this valve so I can swap out one half of it and not cut up the plumbing above it. Can anyone help me identify it?

It's it weird though I did find those but i was worried mine doesn't have the brown on the side of the valve handle. I'm only actually concerned because I'm worried the threads won't match up or whatever.

 

[FUNGI]

you are getting rid of all the plumbing? or just the top?

 

[FUNGI]

I would just cut here and get a coupling to re-attach

I think Cepax uses the "Antiblock" name and others use "Tru-Block" name

Yeah I could do that. I'm just a little worried for various reasons. Its an old elos, that line is the return like and right above that union is the coupling directly into the bottom of the tank. If I mess up that threaded coupling or worse strip the I socket it screws into internally don't know how to replace it. I'm also worried to cut that pipe while it's threaded into the bottom of the tank.

neah...you'll be ok....you got this...
what exactly are you trying to do though?

Ok so it's an old elos tank with quietdrain which is easily the worst designed drain system imaginable. There's two pipes that run through the overflow. A 1.5 inch drain and a 1/2 inch return. I plumbed it that way and it's super loud... which makes sense it's just basically an open drain pipe without a durso or whatever else you might want. There's also no emergency drain. There are some people who say you can make it quiet by adding a true union to the drain but as far as I can tell they are just tuning onto a knifes edge where the return and drain are just balanced.

I want to split the return off and send it through the coveted "mystery hole" that exists in the overflow (it's just a hole that runs straight through the otherwise solid overflow for... as far as I can tell... no purpose) and I want to plumb the return as a full siphon and the enormous standard drain as a trickle/emergency drain.

So the easiest way to do that would be to just split the return line and rerout the pump to the new return and the tank-side of the return to the new drain.

Ok so there's some identifying info on it that was rotated to the back before.

Ok pretty sure it's this one: https://pvcpipesupplies.com/1-2-pvc-industrial-ball-valve-gray-socket-threaded-21979.html

It is CPEX part number 21979. I found one on ebay with precisely the same stickers and formatting (the one in the link looked just a bit different). Hopefully this one has a good chance of fitting together.
