2500 170 650 Valve Plate for Air Brake Compressors

What does a compressor valve plate do?

A compressor valve plate serves as a critical component within the air brake compressor, regulating the flow and pressure of compressed air essential for braking performance. This high-strength component is engineered to withstand the intense thermal and mechanical stresses encountered during continuous operation in heavy commercial vehicle braking systems.

Vehicle and engine compatibility

This part is compatible with various vehicle models, including Kenworth T270, T300, T370, and T470, as well as Freightliner M2 106, FL50, and FL60. It is also fitted to Foton Auman EST, Ollin, Tunland, and various Blue Bird and Volvo models. The part is designed to work seamlessly with Cummins engines such as ISB, ISC, ISF, and ISG12.

Installation and maintenance

When performing maintenance or repairs on the pneumatic system, it is vital to check the plate thickness and seating surfaces. Ensuring the valve plate is free of debris and correctly seated prevents air leaks and maintains consistent pressure. For precise installation, always follow the service manual for the specific compressor housing.

Troubleshooting and selection

Maintaining the integrity of the valve assembly helps prevent issues such as low air pressure or brake lag. Replacing worn components with high-strength parts ensures long-term reliability for fleet managers and workshop technicians alike.
