Is that a de-superheating application?
used for liquid injection to control discharge temperature?
that's typically where I see the "Y" valves
I've got Defrost issues, Refrigeration issues, Store Manager issues....
I suspect improper installation, but I need to prove it. Getting all lost and buried on Sporlan's website. Does anyone have info on a Y-936-AA valve? Thanks....

My thinking is either I've got a valve dumping Liquid straight down the Equalizer line, or I've got a valve designed for Hotgas Bypass incorrectly fitted to the Return as tho it were an Equalizer line.

Looks like your TEV is bypassing liquid into the equalizer line.
Is that a strainer or check valve in the equalizer line?
Check valve.
Your picture shows all kinds of problems, liquid bypassing the evaporator going into the suction line, And a check valve in the equalizer line. And this manager is giving YOU are hard time?
Sheesh, I'm sorry for you
Yeah. I'm unfamiliar with that Sporlan number. I think maybe its NOT Externally Equalized, but is designed for Gas Bypass. I think maybe someone THOUGHT it was for equalization. But I don't KNOW that. Apparently they've had problems with this case for years.
Welp, I guess you could look up the case model number and see if it mentions anything about a TEV with hot gas bypass.
I vaguely remember a Hussmann Y-valve like this from back around 1985. It was intended for KoolGas defrost systems. I think the side connection shown in the pics as an equalizer is intended to be routed back to the liquid line.
Andy Schoen may know about these...unless they were before his time.
Sporlan's valve ID document says any txv preceded with a "Y" is special order made for a specific manufacturer. Most likely have to call the equipment maker to get the valve specs.

Fellas - Thanks for the ideas and the link. Here's what I found:

What caught my eye were pages 3-1 and 3-3.

That's what I remember alright.
These Y-valves were only used for cases with Koolgas and no distributor, so the TXV was internally equalized. Here's a pic I found of the Y-920:
I think I'd just cut all that out and replace it with a standard balanced port valve and a bypass check valve.

Thanks for confirming, Andy. Funny thing is, there's already a Bypass Check in place. Just need to get the powers that be to give the okeydoke. Before another compressor scrambles.
I had nothing to add by the time I read this, but I am impressed by your follow through with this issue. Can see why John speaks highly of you.
