This is a Doising Manifold Air Purge Valve Module that controls the flow of air within the hydraulic system, ensuring proper purging of air. It is manufactured to meet stringent Volvo quality standards, offering superior durability and sealing compared to worn or damaged valves. Operators may notice inconsistent hydraulic pressure, sluggish operation, or audible air escaping from the system when this valve fails.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
Initial signs of failure may include a slight decrease in hydraulic system responsiveness. If left unaddressed, the issue can progress to noticeable sluggishness and potential cavitation within the hydraulic pump. Continued operation with a faulty purge valve can lead to premature wear on hydraulic components.
Ensure the hydraulic system is properly depressurized before attempting removal to prevent fluid loss and injury. Do not overtighten the valve during installation, as this can damage the threads or the valve body.
Inspect the hydraulic fluid for contamination and check the hydraulic filter for debris when replacing the air purge valve module.
