Strength and reliability is the primary factor, something that a diaphragm simply cannot match in a high-boost BOV environment. Diaphragms have their place (we use them in our wastegates), as they offer low friction and good sealing capability. However, a rolling diaphragm is only designed to receive a net pressure on one side, which essentially "inflates" it against the walls of the chamber in which it resides, exactly how it is used in a wastegate
The unique mounting method of the SV52 is one of the ways we've been able to save unnecessary bulk. By eliminating the v-band style mount, the piston and its venting ports can sit much lower, which reduces the overall height to a number others can't match.
The anodized piston bore creates an extremely hard and low-friction surface on which the single piece aluminum 52.5mm piston glides, and will continue to do so over countless cycles. It features an arrangement of Viton o-ring seals unique to GFB
Strength is important, Realizing that a high-flowing valve like this will see duty in some high-boost environments, we made sure the SV52 tops the class in that category as well, giving it an astonishing boost pressure rating of 300psi!
The SV52's unparalleled pressure capacity starts with a monobloc body design, CNC machined from a single aluminium billet that ensures strength without adding unnecessary bulk
Consider these questions when you’re looking for a BOV for your high-powered, forced induction engine: YES! Is 300psi enough? YES! It outflows everything else in its class!
Standing only 86mm tall (including the weld-on Adaptor), the SV52 is 10mm shorter than the nearest competitor, AND flows more.
