The steering wheel is not being operated so control spool (G) does not move.
The oil from the steering pump enters port P of the priority valve in steering valve (EHPS) and the
inlet pressure oil moves the spool (D) to the right.
Almost all of pump flow goes to the loader system (main control valve) through the EF port and partly
flows into the hydraulic tank (21) through the spool (M).
