Schematic for the steering control valve (4) Spool. (8) Pilot oil line. (9) Pressure reducing valve. (10) Backup relief valve. (11) Cylinder crossover relief valve. (12) Shuttle valve. (15) Pilot oil line. (16) Load sensing signal line. (17) Return line. (18) Pressure line. (19) Reduced pilot oil line.The flow of oil to either end of valve spool (4) is blocked when the rotation of the steering wheel is stopped. With no pilot oil flow against either end of the valve spool, centering spring (5) will keep the spool in the NEUTRAL position.When the steering control valve is in the NEUTRAL position, oil from the steering pump is blocked by valve spool (4). The pump then destrokes due to the decreased demand for flow. The pressure in the cylinders is communicated through shuttle valve (12) to the compensator valve. The pump will destroke in order to limit the pump flow so that the pump outlet pressure is equal to the pressure at the compensator valve. If the cylinder pressure is equal to tank pressure, then the pump will destroke to the low pressure standby setting of 3900 kPa (565 psi).In the NEUTRAL position, the valve spool also blocks the oil in the lines to the steering cylinders. When the lines to the steering cylinder are blocked, the steering wheel stays in position. If the pressure in one cylinder line exceeds 29100 kPa 700 kPa (4220 100 psi), crossover relief valve (11) will open. This allows the oil to flow to the opposite steering cylinder.As an example, a left turn is made and the valve spool is returned to the NEUTRAL position. A force which causes the machine to turn to the right is placed on the machine. Since the oil is trapped in the cylinder lines, this force causes the pressure in the cylinder lines to increase. When the pressure exceeds 29100 kPa (4220 psi), the crossover relief valves open. Oil is then allowed to flow from the rod end of the left steering cylinder to the rod end of the right steering cylinder. Similarly, oil that is trapped in the head end of the right steering cylinder will flow to the head end of the left steering cylinder. This will cause the machine to steer back to the right and pressure will be reduced in the cylinder lines.RIGHT TURN Position
