Product Description
The Bendix K022105 Air Dryer Purge Valve Replacement Kit is designed to restore proper purge operation in compatible Bendix AD-IS, AD-IP, and AD-9si air dryers. This genuine replacement kit allows technicians to service the purge valve assembly without replacing the complete air dryer, providing a practical solution for commercial truck air brake maintenance.
The purge valve plays an essential role in removing accumulated moisture and contaminants from the air dryer during the compressor's unloading cycle. When the compressor reaches its cut-out pressure, the purge valve opens to exhaust collected moisture and assist in regenerating the desiccant cartridge. A damaged, leaking, or sticking purge valve can interfere with this process and contribute to air pressure loss or reduced air dryer performance.
Featuring a hard-seat purge valve design, the K022105 is manufactured for dependable operation in demanding commercial vehicle environments.
