Adding Power Beyond, 3-spool hydraulic valve, and T-n-T to a JD 2520

Squatch - Mines got the two hoses, in, and out. I guess at 9 gpm, 3/8" hose is adequate.

Thanks for asking. I feel lucky. I have CML. Wonder drug Gleevec is making it virtually transparent to me at this time.

Sasquatch4100,

Usually the 3pt just dumps to tank, and is the last or only valve in the hyd system. If you are going to add valves, and they must be in series, the last valve before the 3pt should have PB, and routed to the 3pt IN port. The OUT port of that new valve should be routed to tank.

I purchased this Prince RD522CCAA5A4B1 spoolvalve and did not get the power beyond adapter for it ,can I just use the out for return ? I have a john deere 2727 with power beyond and want to hook-up the existing lines say the out on tractor to in on valve and out on valve to in on tractor???

I believe you need the PB. Every valve in series should have the PB to pass fluid downstream. The OUT ports of most valves have a low psi rating. The PB ports are built to take the pressure.

Is this what I need ? then the plug you showed would go in the out port?3/4" NPT POWER BEYOND SLEEVE PRINCE 660312004 . THANKS

No, I would not recommend using that valve with out the PB. The PB is there for a reason, and that is to pass on the fluid and withstand high pressure.

Just about every valve manufacturer recommends running the OUT port to tank. The tank ports on valves are only low pressure.

The OUT port is always a separate port. If the valve does not have a PB capability, don't use it unless the OUT port is going to tank.

If that is the number for the PB sleeve, then use it in that valve.

Look especially how the valve is used in a series flow application in the below link

how does Deere run the backhoe valve, there are only 2 hoses that connect to the hoe. It could be possible that the PB in the Deeres are the last valve in the system and the PB return on them IS to the tank. I will have to look at the Hyd diagram on my 2320 in the service manual. all the PB kit on them is a plug that is put in the adapter and a couple of fittings that go into the adapter to allow hoses to another valve.
