selector valve

[yankeerider]

Is there any updates on this valve. I am wanting to use joystick for the FEL for the angle on the snowplow mounted on my FEL. On the wiring couldnt you use 2 switches for the 3 solenoids. If you installed switches for #2 and#3 and connected the wire that energizes these solenoids to solenoid #1, since #1 has to be energized(closed) for #2and #3 to work?

Not quite. If you simply ran a wire from #2 to #1 and #3 to #1, all 3 solenoids would be energized regardless of which switch you activated. You would need to either activate #1 through a relay, or isolate #2 from #3 by putting diodes in each of the wires to #1.

On edit: you could also do it without relays or diodes if you used DPST switches, using separate poles to emergize the two solenoids.

I also want to control power angle from the bucket curl joystick. I am presently using the Myers plow pump and controls from a pickup but this draws too much from the battery since the alternator is much too small. The additional weight is not very desireable either.
I purchased a 6 port selector that the two output ports are controlled by it's own 12 volt solinoid. I got it from Surplus Center. I plan to use a switch that is ormally closed for curl control and momentary for power angle. I will get busy mounting the valve when it gets back above freezing out there. I am going to mount it then measure and order the hoses.

I don't have this valve, but I am thinking about getting one and others already have it, so we need to get the wiring down for all. I think diagrams will help most people the most.

I agree with yankeerider, the first way suggested for wiring with just two switches (SPST) won't work, but I can't figure how you would wire it with two DPST switches either. I drew up this diagram using two SPST momentary push buttons and two relays.



Comments please. Will this work? Why not? Is there a way to do it with only one relay? Does anyone want to show how to do it with diodes? I think I know how to wire it with diodes, but I know zilch about picking the right diode.

I have this valve, not hooked up yet waiting for fittings and looking hard for a grip with switches. I was going to use 3 switches but the last couple of posts woke me up For sure two double poles would do it. Actually double pole , single throw. means all normally open contacts. 12vdc on one side, solinoid coils on the other .
Case 1 press nothing first set of ports is priority. Valve handle moves first cylinder back and forth.
Case 2 Double pole switch. This means 2 separate switches on the same action in the same housing. one pole closes contacts for the first solinoid . This switches the priority to what ever solinoid is picked next. The second pole closes contacts for the second solinoid. Moving the valve operates the second cylinder
Case 3 Double pole switch wired the same as case 2.

The coils only draw 1.5 amps so the switch contacts are all that is needed.
Thoretically there could be a race condition but just make sure you move the valve handle after you press the switch button.

I am more concerned about what the check valve does in the third port.

Duh! I guess I just didn't look at a DPST switch close enough. Every one just ignore my drawing with the relays, unnecessarily complicated. Just use sunset's drawing.

Can the check valve be removed?

I think the check valve screws right out. Looks like an SAE 8 plug would block it. I am just curious as to what it does. Eventually I will find out.
Mean time I am waiting for fittings and a C & C tilt cylinder . Looking for a grip with two switches that is not gold plated. I was thinking about carving one out of a block of hard maple.

Are you going to use on/off switches or momentary.

Momentary It is not necessary nor a good idea to keep the coils powered up all the time. If you use alternate action you might forget and leave it on. They only need to be powered up when the hydraulic 4 way is one way or the other. AT 1.5A the switches can be pretty small. I have a couple in my hand. Last night I thought I could take some play do modeling stuff and develop the shape for a gripper. Then it would get hard and I could maybe even use it after boring holes in it , cover with epoxy or use it as a model for carving out something. Not so easy. Turns out it is a preety complex shape that feels good in your hand. On the other hand , the contact is not very long so a simple shape would probably work well. I just got a C & C tilt cylinder very nice. with double checks. I have a top cylinder I have had for 15 years no double checks. I notice it leaks down over night but I don't think that matters while in use.

We will await your findings on the check valve. I can't imagine how it would fit in with a double acting cyl. Maybe it was for a non-reversible motor application.

The grip: Exactly what I was thinking last night. Except I was thinking pine or fir for a prototype to make the carving easy. Anyone have any ideas on finding a piece of plastic big enough to make a grip from? Any type of wood would be OK if you have a cab, but without a cab something weather resistant is needed.
