  • Another question about my wagner loader rebuild
  • I think the loader that I've rebuilt is a 200,but I used parts from both loaders. The loader I scraped is a 130 (I think).My question is, the 200 has a flow control valve inline on up lines to the loader arms but the other one didn't, what is the purpose of this valve and why didn't both of them use it and is it nessasary? Thanks and God Bless,Beth and Allen.

  • Looking at the parts diagram it is in the extend circuit for the dipper stick cylinders. The only purpose I can think of is to limit the speed of the lift out of safety concerns. I have never encountered one on any other loader but I can imagine a scenario where a big pump and small displacement cylinders could make it fast enough to be dangerous. Especially if the control valve didnt allow the operator to feather effectively. I would be inclined to leave it out. If the lift is scary fast without it put it back in.

  • I don't know about the "Flow Control Valve" as shown in the Wagner parts manual, but when I rebuilt a Wagner loader, I incorporated valves in the lines which extend the boom cylinders.

    These are a type of "check" valve that allows free flow to extend the cylinder, but restricted flow to lower the cylinder. ...These valves prevent a sudden collapse of the boom if a hose or line blew while the boom is raised.

  • Thanks again,I was thinking along the same line,there is very little difference between the loader I took off and scraped and this one. Although I think the old one may have been a 130 with only 1 double action cylinder on the bucket, where as this one has 2 and the lift arms were different on this one. This one more resembles the 200,I had to use the lift arms from the one I scraped because one of the legs on this one had been broken and rewelded so I junked it and welded new cylinder tabs on this one to accommodate the 2 cylinders. I saved every useable piece from both in case I needed it.When everything gets here I'll try it without the flow control valve and see what happens. God Bless,Beth and Allen.

  • According to the manual the models with single acting lift cylinders did not use that valve. I doubt you will need it with a new 10 GPM pump and valve that you can feather. If you can measure the bore and stroke of the dipper stick cylinders I can calculate the lift time at 10 GPM:

  • All my lift cylinders are double acting, maybe H-800-46, or H-800-88,no tags but that is what they most resemble
