Blow-Off Valves

GReddy BLOW OFF VALVE FV 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.
