Hydraulic help needed. I plan to build another dump truck, but this one will have hydraulics to dump it. I don't know a lot about hydraulic units. If I run the Hydraulic pump from an ESC, (Obviously we have to) do I need a valve to make the box operate, or can I just run the pump fwd/rev to control dump hoist up/down?

IF I must use a valve, I was thinking about this one.

Problem is, it has 4 connection ports, but the hydraulic cylinder ONLY has 2 ports.
