20547525 S2 Valve Plate for Volvo FM12 Trucks

What does a compressor valve plate do?

This compressor valve plate serves as a critical component within the air brake compressor assembly, managing the flow and direction of compressed air. It is manufactured using high-strength components to ensure long-term durability under high-pressure pneumatic cycles. Regular inspection of this component is vital for maintaining consistent air pressure throughout the braking system.

Compatible Volvo FM12 models

This part is specifically designed for use in Volvo FM12 trucks, including variants such as the FM 12/340, FM 12/380, FM 12H/380, and FM 12H/340. It also fits the FM 12/460, FM 12H/420, and FM 12H/420 models. When selecting a replacement, it is important to verify the specific requirements of the compressor unit used in the vehicle.

Installation and maintenance guidance

For correct installation, technicians should compare the port layout and thickness of the new plate against the removed unit. Ensuring the mounting surface is clean and free of debris during assembly prevents air leaks and premature wear. Always check the OE number on the compressor housing to guarantee an exact match for your specific engine and compressor configuration.

Troubleshooting air pressure issues

Monitoring the performance of the air brake system can help identify when a valve plate requires replacement, often indicated by pressure fluctuations or audible leaks near the compressor housing.
