SINOTRUK HOWO T5G C7H Cab Front Suspension Height Control Valve Assembly WG1642440051

SINOTRUK Truck Cab Suspension System / Pneumatic Suspension System Parts Cab Height Control Valve Assembly / Cab Levelling Valve WG1642440051 For T5G C7H

The WG1642440051 Height Control Valve Assembly is a pneumatic control component used in the heavy-duty truck cab suspension system. It regulates the air supply and exhaust of the cab air spring according to the relative height of the cab, helping maintain the designed cab suspension position. The valve works together with the mechanical push rod and linkage. When the cab moves vertically due to changes in load or road conditions, the linkage changes the valve position, allowing compressed air to enter or leave the air spring. This helps the cab return toward its specified operating height. The valve provides automatic pneumatic height regulation rather than simply acting as an on/off air valve. Its operation is linked to the cab suspension movement, allowing the air spring pressure and cab height to be adjusted according to the position of the cab. The WG1642440051 is suitable for cab suspension repair and replacement applications on compatible SINOTRUK/HOWO trucks. It can be used when servicing the cab air spring, height-control linkage, front suspension brackets, or related pneumatic components.
