Core function: Control the disengagement and engagement of the steering clutch: * * This is its main function. By controlling the flow of hydraulic oil to the steering clutch cylinder, the separation (cutting off the power of the track on that side) or engagement (transmitting power) of one or both clutches can be achieved. Control the application and release of the steering brake: * * When a sharp turn or stationary steering is required, this valve usually interlocks to control the brake on that side (the track side with the clutch disengaged), braking the driving wheel of that side track and causing the machine to rotate around the center of that side track. Implementing "single lever" steering operation: Modern bulldozers typically use a single joystick to control steering. Pull the lever backwards to disengage the clutch (start turning), and continue pulling backwards to apply the brake in conjunction (sharp turn). Release the control lever to automatically reset, clutch engaged, brake released, and resume straight travel. The complex oil circuit design inside the steering valve assembly realizes this operating logic. Structural composition: Valve body>Mein straksa, wantaim ol kompleks oil pasej i proses insait.
