20382347 S2 Volvo B12 Compressor Valve Plate

What does a compressor valve plate do?

The compressor valve plate is a precision-machined component seated between the cylinder block and cylinder head of an air brake compressor, carrying the intake and discharge reeds. This part is essential for the compressor's operation, as the reeds seat onto the port openings on this plate to ensure air flows in only one direction with every piston stroke.

Vehicle compatibility and fitment

This specific valve plate is designed for Volvo B12 trucks. For correct fitment, it is vital to verify the compressor housing details, as different compressor types may be used within the same vehicle model. Comparing the port count, port layout, and plate thickness with the removed part is highly recommended.

Installation and maintenance

Maintenance of the valve plate is critical for maintaining air system pressure. When replacing this component, technicians should ensure that the seating surfaces are clean and that the new plate meets the required flatness and thickness tolerances to prevent leaks or pressure drops in the pneumatic system.

Selection guidance

Selecting a high-quality replacement ensures long-term reliability under heavy-duty operating conditions. Consult your authorized distributor.
