Thread: Vintage TXV

I pulled this old timer from an under-counter line cooler at a local primary school. The building was put up in the 1950's and most of this cafeteria is original, and this coil and TXV look like they have never been changed.
When I pulled the inlet to check the screen, I found this interesting feature. There was an adjustable orifice with a dial like setting so you could lower the capacity down from the 1/2 ton rating.
Anyone seen something like this?Experience is what you have an hour after you need it.

I truly love seeing old stuff like this...especially when it has something technically cool about it, like this variable capacity TXV.
Great post baub!
I vaguely remember that name...General Controls Company. As I recall, they had something to do with Parker-Hannafin getting into the expansion valve business.

I saw one like that on a vintage glass bottle coke cooler which I came to find out they used some pretty toxic foul smelling substance in the power head. It was quite a few years ago so I'm not sure what it was? Nice back in the day pictures, Baub.

The unit is in New York state... he might have installed it!
But then who am I to comment- I was built in the 40's!Experience is what you have an hour after you need it.

Well...I figure that valve is about the same age as me.
Only difference is I'm not retired just yet.
