3)Left turn
When the steering control valve shaft is rotated to the left,the control valve spool moves off
center.This connects the inlet port(P) to the one port of each metering pump section and also connects
the other port of each metering pump section to the cylinder.The amount that the spool shifts off
center depends on how fast the steering wheel is turned and how much effort is required to turn the
wheel.
