Blow Off Valve

We offer a high performing piston type Blow Off Valve with either connection for hose or with v-band connection with our own v-band clamp and welding flange. It features a large 50 mm valve; we believe this is the largest valve available with the highest flow capacity. Used by motorsport around the world and is one of our best selling products, even when it´s not related to fueling.

Easy setup and choose V-Band or hose connection
