This is the system that I was originaly looking into.
I am looking at Char-Lynn Steering Control Unit; Series 2 (1500 psi max) Open Center, Non-Load Reaction, Power Beyond.
This valve is meant to have 4 gpm of flow (about the same as a good Saginaw pump). The power beyond port would feed the rear steer ram.
Now, the problem with the power beyond set-up is: Once steering is initiated and since steering has priority, inlet flow will be diverted to the steering circuit as required. Flow out the excess flow port (power beyond) and tank port will vary or stop depending upon the steering requirements. (i.e. The rear steer gets what's left over, probably very little w/ a stock box)
I want to be able to steer the front and the rear at the same time.
1. Is it true that I need a pump with more flow (like maybe 8 gpm instead of 4gpm) and the same pressure (1450 psi)? Or will my psi drop too significantly when I open both valves even having 8 gpm?
2. Has anyone experienced usage of the "manual steering check valve" (converts orbital valve to a hand operated pump for limited manual steering i.e. steering w/ no pump pressure)?
is a web page I have been getting some info from.
I could ditch the "power beyond" and get some shut off valves. 4 shut off valves. And do this?????????
Will that set-up work?????????
There are some "crab" options there too but every time I post the word "crab" on here z50k2 starts talking about gaydom.
