We use them alot on hyd. motors to lock them from turning or from overspeeding when turning an unbalanced load. The valve will have a shuttle and spring and a couple of seat assemblies sometimes using balls.I bet that if you have a two way cylinder and don't run tractor , the hitch will lower when you push lever now.Hope this helps....
