HKS SUPER SQV4 BLOW OFF VALVE (BLACK EDITION)

Now available in a new color - body and upper part painted with glossy black paint and funnel with grainy crystal black paint.

HKS Super SQV (Sequential Blow Off Valve) uses a unique sequential valve structure and a differential pressure control system, which allows for a broad operating range from low boost to high boost. Its Pull-Type relief design ensures stable operation regardless of the amount of boost pressure.

This Super SQV maximizes the charge-response that repeats pressure-charging and pressurized air relief by throttle on and off and supports new generations of turbocharged vehicles.

Factory recirculation valve sound cannot be noticed, but once HKS Super SQV IV is installed, its unique & sharp high frequency sound demonstrates its existence. Super SQV IV significantly increases its presence and improve the engine compartment appearance. To match with the appearance created by HKS Intercooler Piping Kit, the buff-polished casting pipe is included. By both the sound and appearance, Super SQVIV increases the fun to drive.

Features

  • High Quality Aluminum Die-Cast Body - Combines the ultimate in looks and durability in the engine compartment.
  • High Stiffness Metal Die-Cast Valve - Reliable operation
  • Triple Fin Design - Triple Fins set at the center of the funnel produces a dynamic and aggressive sound.
  • Pull-Type Relief Valve Operation - More precise relief of excess boost and is compatible for a wider range of boost pressure
  • Primary Valve (Small) - Lift off the throttle, and the primary valve instantly opens, quickly discharging initial excess boost pressure.
  • Secondary Valve (Large) - Combined with the Primary Valve to provide optimal blow-off operation from low to high boost ranges
  • 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.

【SUPER SQV】

HKS Super SQV (Sequential Blow Off Valve) uses a unique sequential valve structure and a differential pressure control system, which allows for a broad operating range from low boost to high boost. Its Pull-Type relief design ensures stable operation regardless of the amount of boost pressure. The Super SQV will support new generations of turbocharged vehicles.

1.High Quality Aluminum Die-Cast Body

Silver-coated aluminum die-cast body. Combines the ultimate in looks and durability in the engine compartment.

2.High Stiffness Metal Die-Cast Valve

Secondary valve main portion is made of die cast metal. Reliable operation with beautiful looking.

3.Triple Fin design produces "Super Sound"

Triple Fins set at the center of the funnel produces a dynamic and aggressive sound. An optional special Round Fin can be purchased separately for sound tuning.

1.Pull-Type Relief Valve Operation

The Pull-Type valve operation offers more precise relief of excess boost and is compatible for a wider range of boost pressure compared to typical push-type blow off valves.

2.Primary Valve (Small)

Lift off the throttle, and the primary valve instantly opens, quickly discharging initial excess boost pressure.

3.Secondary Valve (Large)

This valve combined with the Primary Valve from the sequential dual valve structure. Optimal blow-off operation from how to high boost ranges without leaking.

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.
