Diverter valve Vs. True third function

[J_J]

This double solenoid diverter valve works as good as any other diverter. They have about 218 of these in stock now. $153.

SAE 8 15 GPM DOUBLE SELECTOR VALVE 12 VDC P15544-1

Here is how the valve is connected.

We are now selling a custom diverter package, and while it is more money than the one from the Surplus Center, it offers some distinct advantages over it:

• Custom engineered and CNC machined in the USA from a solid billet of 6061 aluminum material.
• Port spacing and placement are optimized for the easiest mounting options and smallest footprint available.
• Includes five 1/4" mounting holes to fit any situation.
• Solenoid coils are rated for constant duty.
• Includes a high quality jacketed wiring harness, with sealed automotive grade connectors placed at the perfect place to facilitate easy loader removal. Dust caps are provided as well to keep connectors clean when unplugged. No more cheap crimp-on connectors or home-brew wiring needed. Just find a 12vdc power source (switched off with the key preferably) for a simple hookup.
• Includes a very simple and effective joystick mounted switch that's waterproof and easy to operate with gloves on. No more makeshift buttons or expensive joystick handles are needed.
• Includes adhesive backed rubber tape for under the switch and valve body, helps keep things in place and protect finishes.
• Includes UV resistant cable/wire/zip ties for neat and tidy installation of wiring.
• Detailed instructions and theory of operation.

That's the same valve I bought - I ordered two, and tried recently to get a third - unfortunately, this is the response I got from Surplus center - "sorry, but that was a surplus item and is no longer available, nor will it be. We have no other information on it."

The only types surplus center shows now are dual solenoid, and they're not real clear on exactly how they work.

The nice thing about the one Guesseral linked to is that they STACK - my two will stack, and the default flow is thru BOTH valves to the other side, which will go BACK to the original bucket curl cylinders - then the ports on top will each run their own circuit when I push their respective buttons.


One thing that may help switch life would be a clamping diode across the switch ( or better, across the valve coil) - when you open the circuit, a coil wants to create a big reverse polarity spike and that's usually what takes out switches, contacts, etc - the diode absorbs the spike but still allows the FORWARD current to operate the coil... Steve

Steve, if you still want that type of valve, I just happen to know where you can still purchase them. :thumbsup: They do work well when stacking them is required, or at least easier.

Good folks, maybe you can help me... I have a Landpride Hydraulic Post Hole Digger on a B 7800, which the low side of pressure and flow, but within the Landpride post hole digger hydralic specs. When I attach the hydraulic lines to the bucket curl circuit as directed, I lose the bucket function of course, but it seems like the entire digger stalls easily in the ground. (The pump and valve test out at the factory spec, 1980 psi or thereabouts).
Question one: Is there a difference in the hydraulic motor function if the lines were reversed in the bucket curl circuit (something about regenerating side not as powerful?). I have tried to both ways but can't decide if one is really better than the other.
Question 2: Would there be an improvement in digger performance with a diverter or third function valve. (Ie., less pressure loss through fittings and lines.) Which would be better for an augur? I am inclined towards the package at Ken's bucket hooks based on my excellent experience with Ken and his company if that would work.

Thanks

That's nice...... I like the sealed connectors !

Dave, unfortunately switching the lines, or using one valve over the other will not help your situation much, low flow and pressure are what's causing your HPHD to easily stall.

Where you are correct as usual it really seems like way more work that the other valve, but I guess you have to work with what is available.

The Bosch diverter valve is still available, just not through Surplus Center. :thumbsup:

Do you have a hyd gage in the hyd system?

When your hyd post hole digger stalls out, does the gage reflect the relief valve set pressure.

Your force is limited by pressure and the rpm by the GPM. Your hyd motor could be bypassing also causing a loss in pressure.



You could do a little better using a PTO pump, with more pressure and GPM.

Three wires and six hoses?????????
