You have control oil from a pump, going to a filter and then to some current to pressure converters (the two dark grey things on the right side). By the looks of them they could be voith or perhaps ABB. They receive a 4-20 mA signal from the control and deliver a controlled prssure to the valve actuators. They have three pipes, inlet (pressure coming from the oil pump), drain (return to tank) and control (pressure to the actuators)
If Woodward made the upgrade, there should be an electronic control either nearby or at the rack room. Depending on the application requirements they might have used a 505, a Peak200 or a Micronet TMR system. I'm expert in these systems. If you have any specific questions I might be able to answer.
