SITRAK Two-Position Three-Way Directional Control Valve 811W52185-6060

Operating Principle and Function
As a 2-position, 3-way valve, it features two operating positions and three pneumatic ports.
1. Operating Status: Typically used for "on/off" control or airflow redirection within a vehicle's pneumatic system.
2. Application Systems: On trucks, it is commonly used to control steering assist air circuits, differential lock switching, or pneumatic control circuits for cab suspension and power take-off (PTO) systems. Upon receiving a control signal, it connects the supply port to the working port; when the signal is removed, it shuts off the air supply and rapidly exhausts residual air from the working circuit through the exhaust port.

Precision Positioning and Chassis Assembly Systems
1. Steering Wheel/Tag Axle Height and Pneumatic Locking Control: Serves as the control valve for steering column height or front-axle/tag-axle pneumatic circuits in models such as the SITRAK C7H; controls the inflation and deflation of auxiliary air springs via position switching, thereby adjusting the load-bearing status of the steering assembly and front axle.
2. MAN-Technology Axle (MCY13 / AC16) Systems: Pneumatic circuits for commercial vehicle chassis suspension and axles (drive axles/tag axles), used to control auxiliary lifting or differential switching functions.

Operating logic of the 2-position, 3-way valve
Port configuration: The valve body features three ports (one main air inlet, one working port connected to the actuating bladder or cylinder, and one exhaust/pressure-relief port).
2. State A: In the initial position or upon receiving a signal, the main air inlet connects to the working port; airflow rapidly fills the actuating component (e.g., a follower-shaft bladder) to trigger actuation.
3. State B: Upon switching positions, the main air inlet is internally blocked and cut off, while the working port connects to the exhaust/pressure-relief port; high-pressure residual air within the bladder or cylinder is instantly vented to the atmosphere, achieving rapid pressure relief.
