Description
The GReddy Type FV is a universal 40mm blow-off valve designed for turbocharged vehicles. When the throttle closes, it releases excess pressure from the charge piping to help reduce compressor surge and improve turbo-system response.
FV means “Floating Valve.” Its special construction allows the diaphragm and valve to move independently, providing quicker operation and stable pressure release across a wide boost range. The dual-spring system helps the valve respond quickly under low boost while resisting premature opening under higher boost pressure.
