Plumbing a valve w/Pwr BYD on splitter

mgtd · Feb 27, 2009

When plumbing a valve with Pwr BYD (it is a Cross valve and I installed the Cross BYD sleeve), should you still utilize the "Out" port as a return to the reservior, or plug it? Does it make any difference?

When I ordered the BYB sleeve from Northern Hydraulics, the sales order taker told me to install the BYD sleeve, plumb from there to the "In" of the next valve, and plug the "Out " port of the 1st valve. But something is not working.

Everything is now plumbed and in my initial testing I get no motion from the cylinder connected to this 1st double action valve-(log lift table)-but the next valve & cylinder "the beyond" (splitter action) works fine. I'm certain the cylinder and hoses are good, as I used them off my tractor hydraulics for another purpose recently.

Well he got part of it right. He's right when he says go from the PB port of the first valve to the IN of the second valve, but you need to not plug the OUT of the first valve, instead it needs to go to the tank.

Yes, you MUST plumb the OUT port to the tank/reservoir. This is the only line you can Tee into if you need to.

Which valve is first?
The first valve should be:
IN from the pump
OUT to the tank( can be Tee'd with the other valve)
PB to the IN of the next valve in the series.

Okay, that clarifies it--I place much more confidence in the people on TBN than the salesman. Back to the auto parts store for another hose and tee.

And yes, it is plumbed---pump pressure to #1 valve "in", #1 valve "Pwr Byd" to # 2 Valve "In" and #2 valve "Out" to tank via filter and pressure bypass. I just don't have the #1 valve "out" going anywhere. (plugged)

Thanks a bunch, I'll post pictures after painting & re-assembly.

Hooking up that OUT should do the trick...the OUT port takes the leftover/exhausted fluid from the spool and directs it to the tank.

Thanks again, hose and a tee did the trick.

I am looking at the same basic design, does this look right?

Yes, that is correct.

kennyd I appreciated your knowledge on this stuff.

Timely thread as I am thinking of something similiar. I plan on running a valve as well off my loader PB port to another valve to control angle for a plow blade and loader grapple or other frontend uses. I will set up QC's to the front end somewhere convienient. The diagram by N_Georgia is what I had in mind. I have one twist that needs clarification. My pic below is my setup although may be confusing. Right now my FEL is plumbed off one set of rear remotes. I plan to route via the QC in the pic. From pump to FEL valve and then out to other end of QC in pic freeing up my rear remote and tiding up my hoses a little. I assume while not using the FEL valve (open center) the pump flow will through the valve and to the return. The ? is can I 'T' in where I have shown (or somewhere along that line) for the return from the valve out pressurized from the PB port. The line shown where the QC is feeds the rear remotes...then 3pt......then to the tank. Does this make sence?

Thanks Dave

Dave,

You cannot Tee into any high-pressure lines. The ONLY line you can Tee is the low-pressure RTT (return-to-tank), or what would be labeled OUT on the valve.

Does this answer your question? I am just a little confused about how your machine is setup
