From its unique chirping sound, to the ability to out-perform OEM units makes this a blow off valve one can depend on. The latest HKS Super SQV4 Blow Off Valve employs the same design qualities as the original which involves a pull-type sequential valve structure with a differential pressure control system. This design allows for stable operating ranges from low, to high boost pressures. \u003c\/p\u003e  \u003cp\u003eTypical push-type blow off valves require spring load settings for each vehicle specification. If the spring load setting is too low, the valve may leak under high boost and the desired boost setting may not be reach. If the spring load setting is too strong, it may not open at low boost. The Super SQV will operate under any boost pressure setting without leaking.\u003c\/p\u003e  \u003cp\u003e \u003c\/p\u003e  \u003cp\u003e\u003cstrong\u003eDual Valve Structure, Sequential System\u003c\/strong\u003e\u003c\/p\u003e  \u003cp\u003eAt low boost ranges the Primary Valve opens, and at high boost ranges the Secondary Valve also opens, resulting in linear response and optimal blow-off operation at all boost levels.\u003c\/p\u003e  \u003cp\u003e \u003c\/p\u003e  \u003cp\u003e\u003cstrong\u003eFunctionality:\u003c\/strong\u003e\u003c\/p\u003e  \u003cp\u003e\u003cu\u003eAccelerator ON - Valves Closed:\u003c\/u\u003e\u003c\/p\u003e  \u003cp\u003e\u003cimg src=\"https:\/\/www.hks-power.co.jp\/en\/product\/blow_off\/sqv\/images\/img_04.jpg\"\u003e\u003c\/p\u003e  \u003cp\u003eAs pressure rises in chamber C, pressure is applied to both the Primary and Secondary valves.
