Blow-Off Valves

GReddy BLOW OFF VALVE FV-II  has adapted Floating Valve structure which does not open up when the Surge Tank has negative pressure. For no strong initial load, both quick response under low boost and prevention of the relief under high pressure are together. This is a new generation blow off valve.  

It inherits the floating valve structure that was popular in the previous FV model, while improving with a more sophisticated design, easier adjustment, and even more reliability.

A hand turning detent knob that adjust the preload setting of the spring does not require any tools. It is also now possible to change the direction of the hose union on the top cover, so it can also be adjusted 360°, also without tools, to best suit your installation.


The mounting flange and inlet retain the same dimensions as previous GReddy blow-off valves (TYPE-RS, RZ, and FV) so the TYPE-FV2 can easily replaced any of the older models. Made in Japan.
