please ID this outlet port function (cross double spool)

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.
