| HKS Super Sequential Universal Blow-Off Valve |
 |
 The HKS Super Sequential Blow-Off Valve (SSQV) is a dual stage pull type blowoff/bypass valve. Being of a pull-type valve structure, the SSQV can not physically leak under any level of boost because boost pressure also keeps the valve closed against its seat. The SSQV is actuated by pressure alterations only, not by the rate of pressure or vacuum in the line, which ensures a quick valve response and complete closure when off throttle.
|
|
On typical blow-off valve designs, a large valve is utilized in order to accommodate high boost / high horsepower applications. However, these large valves tend to react slowly and require high activation pressure to open, therefore are not able to activate and prevent compressor surge at light-load conditions. On the other hand, smaller, fast reacting valves do not discharge the airflow capacity required for high horsepower applications and tend to creep open and leak as the boost pressure overpowers the spring on these push type valves. |
| For maximum performance, the HKS SSQV incorporates both a small primary valve for ultra quick activation, along with a larger secondary valve for additional discharge capacity. The SSQV is engineered to initially open the small primary valve at light throttle and load conditions, then sequentially opens the secondary valve for additional relief capacity under high boost and load conditions. The SSQV is constructed of polished billet aluminum, which ensures long-term durability and visual appeal. The mounting base utilizes a circular mounting flange that provides exception flow and complete secure mounting via a C-clip snap ring and O-ring gasket. The triple-fin discharge port design produces a powerful and unique aggressive blow-off sound along with added visual distinction. For Universal SSQV applications, weld-on flanges are available in steel and aluminum for custom installation

The HKS universal valve can be mounted to any custom or aftermarket turbo setup with the use of an universal HKS weld on mounting flange. These flanges are available in a number of materials and pre-welded pipe diameters, so be sure to purchase the flange adapter the is correct for your application. If you are unsure about which flange to purchase, please contact your local performance shop for assistance. These adapters need to be professionally welded on to function properly.
