Good day to everyone!

Please help!

Once we bought this Netstal. It was working fine with a small chiller and there was no problems at all.

But at one time everithing was changed - machine started to overheat very fast and we cant cool it even with much bigger chiller.
I dont really understand anything in chillers power but I know for sure that our thiller can handle 3 200T machines
but cant handle this one Netstal.

Also servo valves started to work unproperly:

- clamping/opening servovalve doesnt keep mold in one position and mooving plate moves slowly.

- loading servovalve (MOOG) - it seems to me that exactly this one heats the oil. Also hydromotor cant keep rotation level
to load 300grams of PS.

Servovalve photo attached.

I ask anyone who knows something about this machine or about moog servovalve to give me some advice!!
