It's seems a like unit is a little too small to require external equalizer
I ordered a new TXV for a Traulsen model G21010, R134A 2 door reach in cooler. The original in the unit has a external equalizer connection, 1/8" swt. I believe I saw two feeder tubes on the outlet side of the TXV.
My question, my parts supplier sent me the new TXV but it is an internally equalized valve. I just today realized so haven't called the supplier to double check the part but could it be this is an updated part and the external equalizer line unnecessary?
The original part# 325-6080-09
The new part sent #325-60080-27, AA 1/4 MC

Take another look at that part #. It should be 325-60080-00.
Also, you can see the parts list on page 17 http://download.partstown.com/is-bin...s/G210_spm.pdf

I see that part # in the pdf. I definitely have a part 325-60080-27, clear as day on the power head.
I guess I am calling Traulsen on Mon to confirm no changes have been made.
How do you guys find all of these manuals here on HVAC Talk? I spend a lot of time googling this stuff to no avail.
It's all good. New valve is internally equalized. Just braze over the old external connection. I've done a bunch.

Why is it that those who complain the most contribute the least?
MONEY CAN'T BUY HAPPINESS. POVERTY CAN'T BUY ANYTHING
Dang....and all these years, I thought that if the TXV fed directly into a single circuit evaporator, it didn't need an external equalizer.....and that if it had distributor tubes it needed one....
Technical incompetence is NOT a sales tool....
Two feed
With that small of evap
You should be fine with internal.
I've converted cap tube unit several times
With internal txv
No problem.
If there is a refrigerant distributor you should be using an eternally equalized valve.
You're good to go.
you only need an externally equalized valve if you have a pressure drop greater than a 2Ί SST drop across the evaporators.
Which would be caused by a large evaporator or a distributor nozzle.
