Power beyond

[MRCONCDID]

Hello everyone
I have been reading the power beyond thred and have a question
looking at the diagrams (great by the way) why cant you T into the pressure side before the FEL to the new valve and then run your return (pressured) to the pressured return of the FEL and also the free flow return back to the free flow return of the FEL
a total of 3 lines 3 T's not counting what ever you are running with your new valve?
Is this just to simple, I dont think I have power beyond on my TC30 w/7308

Next point is there a increase in power with a power beyond or is it just a term used to mark an pressured supply ie a free flowing line thur a manifold?
thanks

You can't "T" into a pressure line before another valve.
Your system is probably open center like most of ours. When you "T" into the pressure line and work the new valve, the fluid will go the path of least resistance ... which is right to the other valve where it can pass through with no obstruction. When you operate the valve to make the fluid go to the work ports, it will see resistance from the cylinders and load on it. It will instead, flow to the open center of the other valve. When you work the other valve same thing happens where fluid will go to the new valve and pas through it instead of to the work ports on the valves.
No, there is no increase in power to speak of using power beyond. Using power beyond keeps high pressure off the other valve's return port in the system. Usually, the return port which is designed for low(er) pressure cannot handle the high pressure it sees as a reverse flow or pressure on it.

That made perfect since, so the powerbeyond port is not just the open side of a hollow manifold or block

No, definitely not. ALL valves MUST be placed in series like 3RRL said...
