Product Description
The Garrett 914959-0004 GVB-50R 50mm Recirculating Compressor Valve (RCV) Blow Off Valve in Silver is engineered for high-performance turbocharged applications requiring precise boost control and durability. Designed by Garrett Motion, this premium 50mm valve delivers superior response, reliability, and airflow management in both street and race environments.
Unlike traditional atmospheric blow-off valves, the GVB-50R is a recirculating design (RCV), helping maintain proper air metering for vehicles using mass airflow (MAF) systems. This ensures smoother drivability, reduced turbo lag, and consistent performance under aggressive boost conditions.
Constructed from high-quality materials with precision machining, this valve is built to withstand high boost pressures while maintaining fast actuation and long service life.

- 50mm high-flow recirculating compressor valve (RCV)
- Designed for high-boost turbocharged applications
- Maintains proper MAF system operation
- Improves throttle response and reduces compressor surge
- Durable billet construction with silver finish
- Engineered by Garrett Motion for performance and reliability
Fitment:
- Universal – Custom installation required
- Compatible with turbocharged gasoline and diesel applications
- Ideal for high-performance builds, street, and race vehicles
FAQ
What is the difference between an RCV and a BOV?
An RCV (Recirculating Compressor Valve) redirects air back into the intake system, while a traditional BOV vents to atmosphere. This makes the RCV ideal for MAF-based systems.
Is this valve good for high horsepower builds?
Yes, the 50mm design supports high airflow and boost levels, making it suitable for performance and racing applications.
Will this eliminate compressor surge?
Yes, this valve is specifically designed to relieve excess boost pressure and protect your turbocharger from surge.
Does this require custom fabrication?
Yes, this is a universal performance component and will require custom piping or mounting for proper installation.
