I have a 325 dual loader on my 4010 I currently have a pto pump running the loader,I want to plumb the loader into the tractors main hydraulic system. I have the return line plumbed into the hitch return by the hydraulic filter,the inlet is plumbed into the pressure sideby the brake pedals, but I have been told that the loader valve needs to be converted to a closed system instead of a open system can someone direct me or tell me where to get parts to do that or tell me if I need a different valve, the valve i have is a gressen valve with a adjustable relief valve in it. It is a 3 lever setup with 1 lever with float in it.
Thanks in advance.

We will need at least a picture of the valve. A model number would even be better. Some valves can be converted easily and others can not be converted.

OK I have looked over the valve looking for a number all I see is a casting number do you know where it would be located?
 

Your loader control valve will need to have a port to accommodate a plug similar to plug(key 12A or 12B) which are closed center plugs. Plug(key 12C) is the open center plug
