Hi!
the valve you are using, is it for closed system or not? or have anything to say?

Regards Jarle from Norway:)

This is the data for a JD 2320

Hydraulics:
Type: open center
Capacity: 2.6 gal [9.8 L]
Pressure: 2421 psi [166.9 bar]
Valves: 2
Pump flow: 3.4 gpm [12.9 lpm]
Total flow: 5.6 gpm [21.2 lpm]
Steering flow: 2.2 gpm [8.3 lpm]

So, you should be using an open center hyd valve.

TractorData.com John Deere 2320 tractor information

Some valves are convertible, in that the valve may be just an open center valve with a shallow plug in the PB port.

An optional PB sleeve or set screw is available to convert the valve to PB.

Another option is for closed center and that is a plug to close off the PB port. The fluid from the cyl ports is the only fluid to exit the OUT port.

If you install a plug in a PB sleeve, that will also make it a closed center valve.

i am using my power beyond port on my 2320...
what type of control valve do i need to tilt my box blade? i want something that will not flot, something i can set so the blade goes to a certain angle and stays there but allows my hydraulic pump to not keep running.
please advise...

Great thread, thanks for posting this.

I have a 4500 with just the loader, no 3SVC or PB or anything. Does anyone know if it's the same under there with the plate, set screw, etc?
