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.

WE REBUILD HYDRAULIC PRESS BRAKE VALVES

Akron Hydraulic has been rebuilding hydraulic cylinder's for press brakes for a long time. We have been in business for over 25 years so as you can imagine we have seen more than our fair share. A few years ago a customer called who was having trouble with the main operating valve on his Cincinnati press brake. It was a basic DO-10 style hydraulic valve and it was bypassing (leaking internally). Our customer had been trying to find a replacement valve but the valve was obsolete. In order to replace the valve he would basically have to refigure his whole machine with a retro fit kit. The retro fit would have cost the customer over $25,000. He had been looking for an option to replace the valve that wouldn't cost half of the value of his machine. Since we were fixing his cylinders he thought it was worth a chance to see if we had any idea what to do.

 

After we disassembled and inspected the valve we found that the chrome on the spool was worn and allowing the bypass. We carefully measured the tolerances between the spool OD and valve body ID. After our measurements were recorded we were able to hone the valve body ID to remove all wear and debris defects. We then removed the old chrome from the spool. The spool was then brought back to match the size of the bore to .0004/.0005 with new hard chrome. After the reassemble we tested the valve and then it was ready to be installed back on the customer's machine.

Since that first valve we have rebuilt valves from all over the United States. We have saved our customer's $1000's of dollars and weeks of down time. Please contact us to see how we can save your company time and money!
