This valve offers a combination of vent and recirculation valve functionality, specially designed for turbo engine applications operating with metered airflow management systems.

Main features:

• Compatibility with the recirculation requirements of the engine management system.
• Ability to convert to recirculation-only mode for stealth operation.
• Brass piston with new sealing technology.
• Adjustable spring preload with upper ratchet-type adjuster.
• Unique conical, progressive spring that maintains boost pressure over a wide adjustment range.
• Unlimited piston travel and flow volume regardless of spring preload amount.

The valve design ensures optimal performance without restricting the travel of the piston.
