I am having problems with the valve assembly on the ML106 loader on my 2615.  I found on a related post that you can get new valves online at a very resonable price.  The Mimco Control numbers on the valve are no help in identifying the correct valve.  The seller of the valve is not a lot of help in figuring out exactly which valve I need.  The information they ask for is: Is it an open center system? Does it have load sensing?  Can anyone answer these questions?
