SECTION 3. FUNCTION 1.Open Center Non Load Reaction 1.Neutral Position When the steering control valve is in the neutral position,inlet flow(P) from the priority valve moves the flow selector spool against its spring.This flow is blocked at the control valve control spool.The signal port is connected to the reservoir(T) through orifices in the control spool.The priority valve will only supply enough oil to the control valve to compensate for internal leakage and maintain low stand-by pressure.The oil at each side of the steering cylinder is connected to each side of the metering pump,this allows a degree of self centering when turning out of a bend. ①
