Greddy 11501665 Type-FV Blow-Off Valve

The Greddy bov fv is a new generation of blow off valve. The unique “floating valve” design incorporates a revised adjustable dual spring system, while maintaining the advantages of the previous models’ push valve structure and silicone diaphragm control. The improved design makes spring preload setting less dependent on the idle, while providing better response, increased valve travel, more air-flow and added resistance to premature valve lift under all conditions. Also maintained is a slimer cnc outlet with discharge ports to draws surrounding air to amplify the blow-off Sound, however this can be replaced with optional re-circulation adapters in various sizes.
