Hella 7.22286.55.0 Secondary Air Injection Control Valve

The Hella 7.22286.55.0 Secondary Air Injection Control Valve is a precision-engineered emissions control component designed to regulate airflow in the secondary air injection system. This pneumatic control valve works in conjunction with the engine control unit to manage the delivery of fresh air into the exhaust stream during cold start and warm-up phases, reducing harmful emissions and helping the catalytic converter reach operating temperature more quickly.

Key Features:

• Pneumatic vacuum-operated control valve for reliable secondary air system operation
• Engineered to OEM specifications for precise fit and function
• Controls air delivery to exhaust system during engine warm-up cycle
• Helps reduce hydrocarbon and carbon monoxide emissions during cold starts
• Durable construction designed to withstand high temperatures and harsh exhaust environment
• Direct replacement for failed or malfunctioning secondary air control valves

When functioning properly, this control valve opens in response to intake manifold vacuum, allowing the secondary air pump to inject fresh air into the exhaust manifold. This process promotes complete combustion of unburned fuel and accelerates catalytic converter heating. A failed control valve can trigger check engine lights, increase emissions, and prevent the secondary air system from operating correctly.
