I have a single spool valve that came cobbled onto my MH tractor, run off a pto-mounted pump. It was in line to run a double acting cylinder, but I'm just assuming that cylinder went up AND down. I've plumbed this valve to run my homemade 3 point da cylinder. But the cylinder only goes up, in one position on the valve, and not down using the other position. If I switch hoses to opposite positions on the cylinder, the same position on the valve makes the cylinder go down, and not up, so the valve is only pressurizing one of the work ports. What's going on with this valve? It doesn't seem to send fluid pressure to the cylinder in one of the two positions. I'm assuming its an open center valve because the center position is returning fluid to the reservoir. Also, only one position on the valve is spring return to center. The other is just "put it anywhere, and it stays" - no detent or spring return. I can't find any numbers on the valve.

This same package applies to any hydraulic system from the largest bulldozer to the oldest and smallest tractor. This short series will take a look at the basic layout of a simple hydraul
