Hella Turbocharger Diverter Valve

The Hella Turbocharger Diverter Valve (also called a turbo diverter valve, blow-off valve, recirculation valve, or boost control valve) helps protect your turbocharged engine. It manages pressure in the intake charge system when the throttle closes suddenly. Hella is an OE-level supplier, and this product line is engineered to the same standards as original equipment.

Key Features:

• Relieves excess boost pressure when the throttle closes, which helps prevent compressor surge
• Helps protect the turbocharger and intercooler piping from pressure spikes and premature wear
• Supports smooth throttle response and consistent boost delivery
• OE-style design and construction for reliable sealing and long service life
• Built to withstand the heat, vibration, and pressure of turbocharged engine bays

A worn or failing diverter valve can cause boost leaks, hesitation, whistling or fluttering noises, poor acceleration, or reduced fuel economy. Replacing it with a Hella diverter valve helps restore proper turbo system operation and drivability. Select the specific part number for your application from the available options.
