I've found a lot of inaacurate/incomplete information regarding replacement of the GC2300 FEL control valve and wanted to share my experience. After getting soaked in hot hydro multiple times, getting stranded with blown orings, soaked right boot, etc. I decided to get a new FEL control valve. After much reading on this and other forums I ordered the NT Brand PLV22RFSTKAB and skid steer coupming from Summit Hydraulics (awesome prices BTW!!!) After getting everything installed I powered the tactor up, no leaks, go to use the joystick and WTF is going on...the up/down and dump/curl are all backwards and since this valve body has regen (rapid dump) and float it's not a simple swap the lines and be done.
Well....It turns out Brand had 4 different mounting orientations which dictate how the joystick opeates. The NT units is the 'A' config which means the valve body is designed to be mounted vertical and the the left of the mounting plate. My OE GC2300 valve is mounted horzontal and on top of the mounting plate, which means I need what Brand calls an 'A3' version. This particular 'A' valve cannot be converted to an 'A3' because the valve has regen and the spool cavities are machined differently and cannot be swapped, plus you need a dofferent joystick pivot. Well NT sells the Brand PLV22TSTKAB, which does not have regen and CAN be converted to 'A3' config. But the conversion parts are ~$250 on top of the $300 valve...no thanks.
So I ended up ordering a MB series 3 spool valve from Brand Fluid Power (distributor) in the 'A3' config. This gave me a dedicated 3rd function lever in addition to the FEL joystick so I can add a hydro top link or whatever in the the future.
Summary - pay attention to the mounting configuration callout in the part number !
