Brother Bob,

If the hydraulic valve is self-actuating, so to speak, as a function of reduced downstream pressure, then the solenoid valves would be a replacement in kind and therefore not needed.

If the actuation of the hydraulic valve tells the pump to turn on, then it would still be needed... Unless you tie the solenoid signal to the pump switch.

I guess as with speakers, a picture or diagram would go a long way. You wouldn't happen to have a P&ID drawn up, would you?
