GFB High Flow SV52 Blow Off Valve ~SPR


Welcome To SPR Parts SPR Parts Is a authorised GFB Dealer

GFB High Flow SV52 Blow Off Valve

Standing only 86mm tall (including the weld-on adaptor), the SV52 is 10mm shorter than the nearest competitor, AND flows more!

Consider these questions when you’re looking for a BOV for your high-powered, forced induction engine:

  • Will it handle the pressure? ... YES! Is 300psi enough?
  • Will it flow enough? .... YES! It outflows everything else in its class!
  • Is it small enough to fit my engine bay? .... YES! 10mm shorter than the nearest competitor!
  • Will it last? .... YES! It comes with a lifetime warranty!

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!

Suits engines with manifold vacuum ranging from 5-22inHg (17-74.5kPa, 2.5-11psi vacuum)

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.

Why do we use a piston instead of the more common diaphragm design? 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.
