Super SQV 3 features include a nickel-plated, die-cast metal secondary valve, which is swaged to the primary valve, a stainless steel C-Clip and spring to increase sealing and durability. To assure buyers that they are purchasing an authentic HKS product, the new design incorporates a holographic HKS logo on the back of the valve, as well as additional HKS logos cast onto the body structure.
The Super SQV 3 utilizes the same mounting flanges as all previous generation SSQV's to assure compatibility with all optional HKS SSQV inserts, recirculation fittings and recirculation kits.
All our bovs are thoroughly tested to make sure the valve opens and closes properly at the set rates on the springs. The allowable errors for valves are controlled within 2%more or less.
The SQV uses a uniqe sequential valve structure and a differential pressure control system which allows for a broad operation range from low boost to high boost.
Customers are welcom to the real test and compare our products with others regardless of design, material, working process, or the actual use of results.
