Valves in Mining Equipment (Joy, PHM, Dove, Komatsu...)

Mining in any enviroment is diffucult on equipment, underground mining of salt presents even more challenges. When mining the salt using continues mining equipment there is always contamination in the air. It's difficult to prevent this contamination from entering the hydraulic system.

Once the contamination has entered the oil supply chances are it will damage the control valves. Salt damage is not a problem as we have been working with several large salt producers. Repairing the control valves on this equipment can greatly reduce your compaines operating cost.

Some of the equipment we have worked on include Joy, PHM, Dove and Komatsu. Mining equipment maintenance is hard work, let us help you make it a little easier. Instead of scraping your damaged valve let us repair them. Reconditioned spare parts can save time and money.

NEW: Fix for Bad Land on Control Valve

We have seen several control valves come in with bad lands.  This seems to be a common problem with Komatsu valves.  This could be due to cavitation in the control valve.

Here is the washed out valve land before repair:
(tough to photograph but if you look close you can see the uneven surface of the first land)
