Next step was deciding on a control valve. I actually tried to find a parker valve like met kit sells (
http://www.metkit.com/catalog_conval.htm), but in the end I went with a Prince sectional valve.
It became quite an involved process for me to decide what I actually wanted to buy. I bought into the need for pilot-operated check valves of some kind. I also realized that hydraulic hoses and fittings are pretty expensive, so I set a goal of simplifying my system as much as possible to reduce cost. On top of that I wanted to have an extra remote, in addition to what I needed for my T&T, and since I was already using three cylinders for the T&T, that meant four control valve sections.
After much torment, I FINALLY decided on using three Prince control valves sections that have built in pilot operated check valves, and one section without the check valves but with a float position. It looked like separate pilot operated check valves would cost about $60 each, and I was able to buy three surplus valves sections from Prince, with the pilot operated check valves built in, for $74 each. This simplified the set up somewhat, as I would now have no need to figure out where to mount separate check valves.
The Prince sectional control valves are actually pretty simple in construction and assembly. Before doing it I did not have a clue as to what might be involved. I am including a series of photos showing what these things are about. I would have been interested in seeing these kinds of photos before I purchased the stuff. Hope some of you guys are interested!
The Prince sectional control valve is made up of three parts. An inlet section, an outlet section, and working sections that are placed between them. This first picture shows the inlet and outlet sections. And the power beyond plug that goes into the outlet section if you want the power beyond feature.
The thing to note is that one surface of each section has o-rings, and the other surface is smooth. These surfaces mate up, and you would get a good seal if you put these two sections together. But without a working section in the middle, it would be a useless exercise to do so. Between these two sections the working sections are placed. Each working section has a smooth side and an O-ring side. The three holes without O-rings are for the rods that hold the assembly together.
Following pictures will show the working sections and things will make more sense.
