please ID this outlet port function (cross double spool)

[mlauk]

there are no other ports on the casting...the only other openings I am not sure about are the two caps on the top of the valve body they are down flat on the face of the body between the working ports...?

Those are load check plugs.

Is there any reason that /pine can not take the sleeve out of the PB, and use that as the tank port.

I think you could for an open center system, but not a closed center.

even though the only port on the outlet side of the valve is machined into the well marked as "BYD" (there is no other port) I see no internal plug or sleeve...

I see no reason this valve shouldn't meet my needs (T&T)...but if I want a third remote at the rear I will have to plumb it with a single spool w/PB before the valve in question...

 

[/pine]

just curious...is there any possibility that one of the return line ports would have been "T"eed and returned to tank?

/pine is your tractor open or closed center?

It looks like a sleeve fitting to me. Take it out and see if it looks anything like this.

It could just be a reducer fitting.

Try and see if you can blow air through the valve. Then see if air can be blown through each of the work ports, to exit out the hole marked PBY.

If it is... Then where is the OUT port?
I believe this is just a generic casting (that's why it's marked OUT and BYD) but is NOT machined for use as a PB valve.

Answering for /pine:

Open

 

[mlauk]

If it's open then I think /pine could just remove the sleeve, plug or whatever is in the power beyond port and use it as the out port to the tank like JJ suggested.

It is either a special purpose valve, or someone forgot to bore the tank outlet hole. A similar Cross valve has the tank port beside the BYD port.

I think there may be some confusion here (probably my fault...)

I have plastic plugs in all the open ports for cleaning/painting sorry I did not mention that....

After heeding the insights presented I think we have determined that the port marked "BYD" is actually the "OUT" port...and this valve does not have PB capability...

I'm thinking this was a contract production valve produced for an equipment manufacturer...

The reason I asked about a possible "T" at one of the returns...was...when I got the valve there were JIC connectors on all the ports except one of the returns...? I know it does not mean anything....

thanks for all the feedback...

So that is a plastic plug in the BYD hole. Sure did fool me.

Not recommended, but I have heard of a few that feed other 'down line' valves via the T port with no ill affects.
