The HKS Super Sequential Blow-Off
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.'
