The HKS Super Sequential Blowoff Valve (SSQV) is a dual stage pull type
relief valve. Unlike other blow off valves that are push type, the SSQV will
not leak under high boost conditions nor under vacuum at idle. 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 during idle.
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. The HKS SSQV is available as a universal unit for custom applications and also by vehicle specific
kits for bolt-on applications. Vehicle specific HKS SSQV kits come complete with
all needed mounting flanges, brackets, and miscellaneous hardware for a bolt-on installation. For Universal SSQV applications, weld-on flanges are available in
steel and aluminum for custom installation.
