Description
Four Wheel Steer Switching
Valves provide three different
types of steering by
energizing and de-energizing
two DG4V-3 valves. DG4V-3
valves are high performance,
solenoid operated directional
control valves.
• Two Wheel Steering:
Energize Solenoid S1
• Four Wheel Steering:
Energize Solenoid S2 + S3
• Crab Steering: Energize
Solenoid S2 + S4
