Blow-Off Valves

GReddy Blow Off Valves are easily adjustable to eliminate compressor surge and preventing premature boost leakage, while increasing boost response between shifts. Each valve is made of durable cast and billet aluminum frame and the valve to diaphragm ratio provides performance that cheap piston types cannot offer. The spring stiffness adjustment screw and the three different models give the GReddy user the option to match vehicles with mild upgrades to heavily tuned engines.  - Blow Off Valve FV2

Item Type Size Description PART #
Blow-off Valve Type FV II 40mm

Floating Valve Design with Detent Knob - NEW

11501666
Item: Blow-off Valve
Type: Type FV II
Size: 40mm
Notes:

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.
