GFB T9052 SV52 Racing Blow-off Valve

In the race to create the most compact and highest flowing blow-off valve, GFB’s SV52 pulls ahead of the pack.

Standing only 86mm tall (including the weld-on adaptor), the SV52 is 10mm shorter than the nearest competitor, AND flows more!

The SV52’s unparalleled pressure capacity starts with a monobloc body design, CNC machined from a single aluminium billet that ensures strength without adding unnecessary bulk.

The anodized piston bore creates an extremely hard and low-friction surface on which the single piece aluminum 52.5mm piston glides, and will continue to do so over countless cycles. It features an arrangement of Viton o-ring seals unique to GFB.

The SV52 also includes 2 springs PLUS a spring pre-load adjustment system so you can dial it in for optimum throttle response and boost recovery after gearshift, without resorting to the costly hit- and-miss approach of purchasing extra springs
