The Garrett GVB-50 is a 50 mm vent-to-atmosphere blow-off valve that releases boost pressure when the throttle closes, protecting the turbo from compressor surge. It is CFD tested for maximum flow and thermal efficiency, with a fully machined billet housing, anodized 6061 aluminum actuator cover and a high-temperature Nomex-reinforced diaphragm. Eight stainless steel springs let you set the opening point from 3 to 13 PSI, and the flange dimensions are interchangeable with Tial Q and QR valves.
