The purge valve is a critical component of the AD-9 air dryer system, responsible for expelling accumulated moisture and contaminants from the air brake system. During the purge cycle, the valve opens to release water, oil, and other harmful contaminants while reactivating the desiccant material. The soft seat design ensures proper sealing to prevent air loss and maintain optimal system pressure. Haldex remanufactured products are built using superior components and precise manufacturing processes to meet or exceed OEM quality standards.
