I can make this point only when talking about hydraulics for machines. An open center valve is a valve that has the pump pressure going to all the ports in the valve, both cylinder ports and the tank port. THis would mean that the pressure of the system would only be say 100psi, just enough to push the fluid through the lines and back to the fluid holding tank. A closed center system is where the fluid going to the main valve is blocked at the pressure port and you would have to shift the valve to get pressure to the cylinder ports.
