I made my valve box out of PVC trim board. A little expensive, but worked out great.
The valves were originally installed in a 6-up plus a 2-up valves boxes. By the time I needed to service them, the valves were half covered in mud, and there was not enough room in those boxes to work anyways.
My box has a bottom, and a close fit on the lines. So far has done excellent job at keeping the valve area clean. The PVC boards can be solvent welded with the same PVC cement as you use for pipe. No fasteners at all on my box. I had some grey cement which is not very visible on white, but you can get clear too. First thing I did was a test on some scrap PVC boards to test the strength and the joint is stronger than the parent material.
Not sure if your plan on putting the valves 2 feet down is going to work out unless you bury the valves with two feet of dirt.
