No. Regulated/Transmission system pressure is one and the same thing and comes off of one of the gear pump. Low-pressure standby and high-pressure standby are the operating limit pressures of the piston pump.
All the remote valves and the hitch valve use regulated pressure for pilot pressure to move spools in the valves to direct signal & piston pump output pressure where it needs to go.
You need both regulated pressure and standby pressures to make those valves all work properly. If regulated pressure is low, the spools will not move properly.
Ok makes sense but would you think 200 psi would be more than plenty to move those pilot valves?
Seems to me I’ve had a unit with low system/trans pressure from a blown piston seal that the remotes still worked fine.
Where does system pressure feed the control valve stack? I was looking on parts site but can’t locate it. |
