I bought two of these
12 VDC 13.2 GPM SAE 8 DOUBLE SELECTOR VALVE
for front hydraulics on my 580B - one will be used for a grapple (yet to be built) and the other to articulate a Samurai sickle bar cutter for doing hedges, etc -
Mine actuates
BOTH sets of ports with one solenoid, yours will actuate ports
SEPARATELY if you want - but for what you want to do, I would wire both solenoids in parallel to one momentary switch on your BUCKET circuit control lever - that way, one hand on the bucket lever, with no switch, bucket curls. Switch, and thumb operates while bucket stays put. You will need both pairs of ports, one for pressure and the other (depending on whether you're extending or retracting the thumb) for tank return. That's why you'll need to wire both coils to the same switch.
By doing that, you can pre-position either the bucket OR the thumb, then use either one to grab stuff. Or, you could "sneak up on your load" by alternating bucket-thumb-bucket til you have it the way you want.
If you still want to use your outrigger circuit, it'll work - those valves block off whichever port is
NOT actuated, so wherever your outrigger is, it will
STAY there til you switch
BACK to using that control for the actuator. (Leaks being the exception)
Not sure about
YOUR hoe, but my Case has
MUCH smaller ports on the outriggers (3/8 instead of 3/4) so, for
THAT reason, the outrigger circuit might be your better choice - the lower flow would give you a
LOT better control/finesse.
HTH... Steve
Missed one point - if you use the outrigger,
THAT should be the
DEFAULT (as in, no power applied = outrigger) - most that should happen, if you shut the hoe off with your finger on the (momentary, remember?) button, you might get a small "twitch" in the outrigger...
