FITMENT NOTE: For the universal blow off valve, it needs to be welded on with the use of a flange. We highly recommend purchasing the GReddy flange (includes bolts and gasket) to ensure a clean install. Also, these valves are designed to vent to atmosphere only. They cannot be set up to recirculate.

The new GReddy Type FV Blow Off Valve is designed for use with low to mid boost applications producing less than 420 hp. The Type FV features a 40mm floating valve design and is easily adjustable to prevent both premature boost leakage and compressor surge. The floating valve alows for improved control, response, and idle. In addition, the new top hat design allows for rotating of the vacuum nipple without disassembly of the unit. The GReddy Type FV blow off valve is made of durable cast and billet aluminum frame and the valve to diaphragm ratio provides performance that cheap piston types cannot offer.
