Hydrolic Value
--------------------------------------------------------------------------------
I have a Jinma 284 with a Spirit SL-20 Loader. The tractor was purchased in 2005. It has 2 Control Levers and the Value Box pushed out from the inside cracked when the loader was removed from the tractor.
I want to replace it with a Single Joy Stick. I talked with the Surplus Center.
They asked me some questions, I can't answer.
1. Can someone tell me the GPM?
2. Is it Open Center or Closed Center?
3. If it is closed center does it have load sense?
4. What type of pump (Gear Pump)?
This is the valve I am going to order if it will work. Will I need anything else.

Your tractor is OC (open center). The 9-7401 valve will work perfectly.
