Description

This compressor valve plate functions as a precision-machined component seated between the cylinder block and cylinder head of an air brake compressor. It carries the intake and discharge reeds that open and close with every piston stroke, ensuring air flows in only one direction to maintain proper pneumatic pressure within the system.

This component is designed for use in Volvo FH12 trucks, including variants such as the FH 12/420, FH 12/340, FH 12/380, FH 12/500, and FH 12/460. It is essential for maintaining the efficiency of the air brake compressor in heavy commercial vehicles.

When performing maintenance or repairs, technicians should inspect the plate for any signs of uneven wear or debris that could prevent the reeds from seating correctly. It is vital to verify the port layout and thickness against the original part to ensure a perfect fit during installation.

Proper selection ensures the longevity of the compressor assembly and reliable braking performance for the vehicle.

How do I know if this valve plate fits my compressor?
Vehicle model alone is not sufficient. You must check the OE number on the compressor housing and compare the port count, port layout, and plate thickness with the removed part.
What is the function of this component?
The valve plate carries the intake and discharge reeds which open and close with every piston stroke to ensure air flows in only one direction within the compressor.
Can this part be used in other Volvo models?
This specific part is designed for Volvo FH12 variants. Always verify compatibility with your specific engine and compressor configuration before installation.
What are common signs of a failing valve plate?
Symptoms may include loss of air pressure, irregular compressor timing, or audible leaks from the compressor housing due to improper reed seating.
What are the OE reference numbers of this part?
13 01 12 directly replaces Volvo OE number 20547525S2.
