PB vs. Tank

[Oliver1655]

I'm definitely not an expert.

- On my splitter, I have 4 Energy valves connected in series, none with power beyond.
- The pressure reliefs are factory set at 2,500 psi.
- The last valve in the series is the "log splitting valve.
- I am able to use any of the other 3 valve while splitting but as part of the flow is being diverted, the splitting cylinder will slow down.
- The main reason I have for switching to PB valves when I build my next splitter is the the primary reason most have gone to PB valves, BACK PRESSURE! As the pressure builds up to split gnarly pieces, it puts reverse stress on the valves in front of it & the connections between them. The only leaks notes are the NPT joints connecting the valves together. The detente on the splitter valve is starting to stick occasionally. This may be related to not having PB.

The relatively small difference in price between PB valves & those without is minor compared to the added stress/wear on valves without. Again with my next splitter, I will be using PB valves.

This excerpt is from Energy.

Consult factory if back pressure of over 200 psig (14 bar) is present.

Who did the installation?

Because the flow will take the path of least resistance.

So if you actIvate the lever for operation, you offer resistance, then the fluid will go through the other valve.

Got it, thanks JJ..

When I did the last system on a small tractor, I had to have Energy spec a valve that would handle back pressure. I had to use the oil twice once to drive a implement and then the fluid had to be reused to drive the tractor. Energy techs suggested a DCVA series valve and it has been working great. With the addition of a main relief, that eliminated any stalling problems from the previous hydraulic expert that built the system. We also added power steering. I now know more about these little Case tractors than I care to! CJ
