Power beyond

What are you trying to 'run' ?   

MrSnerdly wrote: A small hydraulic pump on an Ace sprayer.  The tractor has two remote valves but they have to be used to raise the left and right booms on the sprayer.   A third remote would work but that would end up being a lot of work and expense.  A power beyond would be much simpler.  I know the PFC system needs to be done a little differently than a closed center system.

I’d look into a multiplier for the boom raising function and run the motor off the other.

Certainly just opinion here, but I would lean toward an electric diverter valve plumbed in the lines plugged into one of the remotes. To me, that seems the easiest way out for something you don't need to be a permanent part of the tractor. 

Could you just change pump to a pto driven pump? Could be cheaper option.

Just trying to think outside the box here. I don't think you need a "Power Beyond valve". I think you need a Load sense/closed center valve that stands alone. Tap or tee into the output of the main piston pump for your oil flow at the pump. Tap or tee into your load sense line for signal to the pump at the pump. Return oil should go into the surge chamber line (another tap/tee) but could probably go into the lower sight glass or the plate above the drawbar. Your new valve would need a flow control for speed. I envision the area behind the lower battery tray being used. I think an electric add-on with left/right switch for booms is the best idea.

The switch is a 3 position switch, center position off, left on, center off, and right on

I don't mean to get to techy or simplistic here, but a definition can be helpful. Power beyond in  hydraulic terms means an outlet for pressure to operate hydraulic functions under full flow and pressure to another valve system. Example is on a tractor with out any remotes or loader the pump pressure goes to the lift system on the 3 point hitch. IF remotes are added the pump flow goes to the valve - thru the valve and then out to the 3 point hitch via a 'power beyond' fitting or sleeve.  If a loader is added with a joysitck the flow goes to the loader - out through a power beyond - and to the tractor remotes - out thru the power beyond to the lift.  Most valves with a power beyond have a 3d line to sump that takes the flow from the cylinders return oil on the non pressure side as the ram moves from pressure on the other side of the ram. Auxiliary valves have an inlet and outlet standard. IF the oulet is used as a point to provide pressure with out a power beyond sleeve it will pressurize the oring seals on the spools and will soon fail them. There could also be a restriction of flow causing overheating.  This is on an open center system. On a closed center valve the power beyond is blocked as one can Tee into the pressure line anywhere for more valves.  The pressure flow compensated valves that are added into the PFC units must have a 'sensing' line with a one way check tee to 'stroke the pump'. This is a special valve.     

I have a Fasse switch on our 8050 for the 3rd set of remotes. works great on our Kinze planters but as said above need to flip switch from one to another. Which for me is only when going to or from transport. Question I have is if he wants to raise or lower booms while the pump is running, will the boom remote starve or slow down the pump remote, dropping water pressure or not raising the boom without shutting off pump remote? This would be the same with a Fasse valve or adding an additional remote to the stack. 

The electric valve has two hoses on it. Just plug into a remote valve like a regular hydraulic cylinder would. Flip the switch left or right and operate the remote valve lever up or down.

Here is my Fasse valve on an 8050. In the pic I have 2 sets of hoses hooked up, don't need the third for our grain cart. But a must for the planter. The chain goes up to the cab to help support the weight of valve and hoses. The wires go from valve to switch in cab. The switch is a 3 pole, off in the middle, hot left (b for black wire at solenoid) or right (w for white wire at solenoid). That just helps me figure out what I'm doing when hooking up different pieces of equipment. The Fasse valve has eccentric hyd inlets to fit your tractor remote. They sell for about $500. I'm not sure if this is the same as the electric valve Dr Allis is talking about.
