Good evening to everyone. I am looking for any kind of literature regarding a Sporlan manufactured valve which has a label on it reading Y825-2. I havenīt found anything in the sporlan website.
This valve seems to control de oil flow from the separator/reservoir to the mechanical oil level controls at each compressor. I am confronting a low oil level situation in a R-404 low temp rack system including 9 compressors, and the only adjustable device in the entire oil supply system is this valve (oil level controls are non-adjustable). The oil separator seems to be working properly, keeping an oil level well above the bottom sightglass. Oil system filter is brand new. I guess this valve must be a pressure reducing valve, but i have no clue about its adjustment. If you know of any site with any information on this kind of valve, please let me know. Best regards.

I am guessing the Rack is a Hussman Rack. The adjustment for this valve is under the bottom cap. CW = increased differential.

Yes a specific model for Hussman.

Nearest is the Y1236C, look at document 110-10 here...


Be aware that there is a safety warning on some early versions of your valve...
