ABS hydro module's valves state while driving

[YuriB]

All manuals I found describe how hydro module of ABS works, when braking - how input and output valves are opening and closing depending on the braking processes - but no one describe their state during driving. I guess the input valve is of NO type and de-energized while driving. Is the output valve's solenoid energized and the valve (NC type) remains in the open state during normal driving ? Pressing braking pedal, does its switch de-energize and shuts close the output valve ? Thank you !

No the output valve is NC and not energized in normal driving. OV is only opened when the system pressure needs to be reduced.
