Description

The heavy duty air dryer valve is a critical component within the pneumatic brake system, ensuring the removal of moisture and contaminants from the compressed air stream to protect downstream components. Designed for durability, this complete assembly provides reliable air regulation and moisture control for heavy commercial vehicle applications.

This component is the OE-equivalent of the KNORR-BREMSE I87501, I87501003, I87501RP, II30448, K028021, and LA 6210 air dryer valves used in KNORR-BREMSE systems. It maintains precise pressure regulation at 8,1 BAR to ensure consistent braking performance and system safety.

For workshop technicians performing maintenance or system overhauls, this unit features a 24 V heater to prevent freezing in cold climates. The technical specifications include Port 1 (M22x1,5), Port 21 (M22x1,5), Port 22 (M12x1,5), and Port 4/23 (M12x1,5). Proper installation ensures optimal pneumatic flow and prevents moisture-related failures in the braking circuit.
