The Garrett GVB-50R 50mm RCV blow-off valve in blue is a recirculating 50mm valve designed to return excess boost to the intake instead of venting to atmosphere. Sized for 50mm connections, it preserves metered intake flow while protecting the compressor from surge on throttle lift. Use the blue GVB-50R when a 50mm RCV blow-off valve with that finish is required by the application.
