Dear Maintenance and Engineeering Professionals of MAPP:
I am having issues with the the MM Series Milacron Presses.
We have had several failures on a Hydraulic Prop. Valves on these machines. The valve is a Bosch Rexroth Prop valve. The stack valves have the following numbers: One valve # starts with 4WRAP6 and the other starts with # 4WRKE25R5.
The Milacron Part # is 5073286 13, the description is VLV, PRP NG25.
Has anyone else with these machines had failure problems with this valve?
We have it failing on the MM880, MM580, MM450 and MM310 Milacron size presses. (All the presses take the same valve to control the clamp motion.)
If anybody can clue me in as to why these vavles are failing it would be greatly appreciated. I will take any information and resources you have to offer.
