electric hydraulic valves with toggle switches

[kennyd]

I can't really tell what the consensus is. Seems to be that the lack of a true feathering operation with a standard DC solenoid valve isn't a big issue for most front remote users (for low flow operations anyway). So maybe my problem is a theoretical one? I certainly haven't seen any complaints about it being 'jerky' or hard to control.

Exactly. You will not find one thread/post here saying they where unhappy after installing a solenoid valve.

This also got me to looking more closely at the component parts of a front remote system, and i'm wondering if it's safe for a rookie to build one rather than source it commercially. The component parts seem pretty straightforward, and it seems that it could result in saving a few hundred bucks. I wouldn't be crimping any lines myself, just knitting the parts together like i imagine i would be with a commercial kit anyway. Any thoughts on that?

You can buy all the "parts" of the kit separately if you want, but in the end the savings will be small if you value you time and add all the shipping from various vendors.

Thanks Kennyd. I'm basically buying a bunch of stuff at once and it has me in decision overload, lol.

Definitely place more value on time than I used to, may just 'get the kit' and be done with it.

Thanks!

Safe? Well, anything can be done incorrectly, even if you buy a turnkey
kit with instructions. Some folks are more DIY than others, and some
are more cost-sensitive than others. The WRLong kit is much more
expensive than its components, but some people would rather pay the
premium rather than figuring it out for themselves. Nothing wrong with
that...there is no consensus here.

It is very important to note that diverting a work circuit off another
valve is very different from using a solenoid valve in the implement pump
circuit independent of any other valve's work ports.

I think i want to explore the DIY option a little more. Northern Tool seems to have a great collection of solenoid operated valves here:

Power Solenoid Hydraulic Control Valves | Hydraulic Valves | Hydraulics | Northern Tool + Equipment

I just need to study up on the elements of a circuit and figure out what all is needed (prv if i come right off the pump/manifold/whatever?). I don't even know whether the Bobcats are open or closed center...hoping i can figure that out when the rig arrives later today (w00h00!). Nothing like a little bit of homework to rev up the weekend.

I did notice that none of the valves in the above list have current draw specs. Obviously the thing will need to be fused, hoping that there's some kind of reasonable attachment point for accessory electrical on the tractor.

Already have an idea for the knob switch, just need to customize it a bit.

Thanks J_J! I like the form factor of that valve a lot more than the others. I don't fully understand the control function when the solenoids are in different energized states, I think I just need to sit down with the diagram.

Here is the way it works. With no power to the valve, the hyd fluid goes to the curl function. The valve itself has one circuit open, and one closed. The grapple is connected to the normally closed valve ports. When the switch is activated, both solenoids are activated, and the valve that is open, closes, and the valve that was closed is now opened, allowing fluid to switch to the grapple circuit. The switch can be a SPST switch, or a momentary switch like the button on the handle. When you release the switch of turn it off, the circuit reverses to the no power mode.

There are two valves that are similar, so be sure to use this number.

Item# 9-5117-A

Be sure and wire in a suitable fuse.

The one he linked is a "diverter"valve, I thought you wanted independent control?

I do, I wasn't quite sure how to interpret the description of the different solenoid states. Fortunately my CT235 'demo' showed up about an hour ago, so A) i get to play on it in some beautiful weather this weekend and B) i can get an up close look at the plumbing to figure out how all of this should go together. I'm learning first hand that a CUT with no ballast does not a digger make. lol

It can make a broken front axle if your not careful
