Dual Valve Structure, Sequential System
At 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.
-
Accelerator ON
Valves Closed
As pressure rises in chamber C, pressure is applied to both the Primary and Secondary valves. The higher the boost pressure, the more pressure is applied to the valves, preventing leaks.
-
Accelerator OFF
Primary Valve Opens
Throttle lift creates a pressure difference between chambers A & B, opening the primary valve bypassing the secondary valve. this creates the initial discharge.
-
Accelerator OFF
Secondary Valve Opens
When pressure difference in chambers A & B reach a maximum, the Primary Valve pulls the Secondary Valve open, creating a secondary discharge.
Pull-Type blow off valves will work for any turbocharged vehicle, from stock to highly tuned.
Typical 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.
*when Black Edition HKS BOV's are out of stock , metallic silver HKS BOV's are automatically substituted
