Tripple selector valve

[Hooked_on_HP]

I bought the tripple selector valve (155-5569-gp04) from SC. My plan was to hook it up to the control valve for the FEL. The first set of ports would control the FEL functions(curl and dump) and the second set would control the grapple and the third set wouldn't be used for now.So far I haven't been able to get it to work properly.I have the restrictor removed. When I had it hooked to the curl-dump side of the loader valve the regen circuit of the loader control valve was affecting the grapple control( i assumed). I switched to the up down side of the loader control valve and the grapple works fine but the loader always is slow in one direction.If the loader goes up fine and down slow and I switch the hoses around the it goes down fine but up slow Also the higher the rpm's on the tractor the worse it gets. The way it is now it goes up fins and down slow. If I raise the bucket up and shut the tractor off then it goes down fine.With the tractor running and the loader raised, I try to lower the loader fast I can hear the hyd. pump groan. If I push it to the float position it goes down fine.I took the valve apart and couldn't find any blockage. I am about to give up on this valve. Does any one have this valve hooked this way.

I have no personally experience with that valve, but my first guess would be that it's electrical. That thing looks confusing to get those solenoids powered/un-powered properly

Of all the people that bought these valves and talked about them...I am not sure anyone is really using it yet?

I spent the day jacking with this thing. Now I have it back to using the curl/dump function of the loader valve. This is the lesser of two evils. the bucket curls back fine but dumps slow.The grapple works fine. This is the best I could come up with. I am thinking this valve just wont flow enough on the return side. When they say this valve flows 12gpm max I wonder if that is 4gpm per section of valve. At low rpm's(low hyd press) it works perfect.

I am using it . All three ports . Works fine on T & T and blower
Wierd and frustrating issue here. Since the grapple works I would guess you are picking the solinoids correctly.
Problem is curl dump in the priority mode i.e no power on any solinoids.
Big guess here knowing nothing . Since the only thing different in the curl dump is the regen feature, maybe there is somekind of back pressure issue on curl dump.

Are both the check valve and restrictor removed? Are you confident that the solenoids are operating in the correct sequence?

 

[Hooked_on_HP]

I did remove the restrictor and even tried putting the restrictor back in.The problem is worse with the restrictor. If my understanding of this valve is correct the check is in the 3rd function and I am not using it.
Bob on your set up you are controlling the selector with rear remote. For t&t there isn't a lot of flow and you are probably using 1/4 hose. My loader cyl. are 2.5 dia. and 4ft long and uses 3/8 hose so it takes alot of fluid. I also though it was the regen causing the problem so I switched to the up/down side of the loader control and still have the problem. I am open to ideas. I am to stubborn to give up yet.

How much slower is your cylinder moving now? Aren't you saying it is only slow in one direction?

How about taking the bucket off and seeing if it behaves the same way? i.e take the load off the cylinders.
My top cylinder is 2" 16 "long or so goes up and down at good speed. With a snow blower on the 3 point. That one is on the check valve. I cannot see how the vol of oil would have any bearing on this. Are you getting full voltage on the solinoids? I had a grounding problem for a while. One other thought I think it is important to pick and hold the solinoids before moving the 4 way . I have a selector on my front and if I move the handle before picking the solinoids funny things happen. Thats a different selector valve but the function is the same. I find I have to push the botton and hold it for around a second .

Tomorrow I will try running a ground wire to the battery and see if it helps. I assumed the electrical was fine since the grapple works and the loader is fine in one direction. I might also try unhooking one cyl. and capping the the lines to see if it makes a difference. I am sure the loader valve and cylinders are fine because sat. I put everything back to origional and every thing worked perfect.

I may have figured out the problem. I went back to SC's web site and reread the specs on this valve again. Here is the last sentence.First selector has a built-in restriction to restrict flow to the actuator (example: for use with a grapple). This is another restrictor not the .045 removable one in P1. Now I just need to figure out how to eliminate it.

Let us know, I'm just about ready to pull the trigger on that valve....

I see it says that but I do not think it is correct. I have attached the Cat information and it does not show anything but the restrictor in P1. That restricts everything, why would they add another restrictor in the first selector?
But then again maybe there is one. But if there was it would work in both directions.

 

[Hooked_on_HP]

Bob, I have the Cat info you provided, which I thank you very much for, and what you are saying makes sense. I wonder where SC got the info on the restrictor. I wish I knew who actuallyt made the valve so I could contact them.
Bill

Here is the latest. I moved the hoses for the curl/dump from C1A and C1B to C2Aand C2B and moved the grapple to C1A&B The loader works a whole lot better and now the grapple moves slower closing. So there has to be a built in restrictor in the first selector. I guess I am going to have to disassemble the valve to figure out how they restricted it.
Bill

 

[6sunset6]

It could be the size of the galleys. Thats the porting through the valve body. But I would think taking out the .o45 would open it up. Thats why it's in there.

 

[Hooked_on_HP]

I totaly dissambled the valve . All the passages are the same size. They are restricting the flow through the spool in the actuator. In the fist pic you will see the difference. They are restricting it by making the oil flow through 2 holes drilled in the spool on one end of the valve and on the other end the spool is smaller and the oil flows around the spool. The way this valve works is the spool blocks or opens ports in the outer piece of the valve(dont know the correct name) The big problem I found is that the spool is only opening the lower ports 1/2 way. The upper ports are fully open. This will restrict the flow. I think this is a manufacturing defect. I don't know if this is a problem with all these valves or just mine. I am going to try to machine the outer piece of the valve so the spool goes in farther(about .020) so the ports fully open. I will try to get some better pics tomorrow
Bill

 

[Hooked_on_HP]

Here are some better pics. The 1st pic shows the spool valve. The 2nd shows the spool installed. Notice how the lower ports are partially blocked. The 3rd shows the end of the valve I am going to machine.I need the make the recess about .030 deeper.
Bill

BTW these pics were taken through a magnifing glass.

 

[6sunset6]

Bill, How are you making out?

 

[Hooked_on_HP]

Well Bob, for now I have put it on hold. I am still having the same problems. When I get caught up on things arround here I will play with it some more. I thing I found out by accident was that if you put power to #2 without power to#1 both will function at the same time. When I get back to it I will let you know.
Bill

 

[mgamber]

Is there an update on this? I got mine hooked up today and I think I have the same problem. My curl UP is slower than before. I think I can live with it but would like it to function like it did before.
