Precision Turbo and Engine (PTE) released its new PB64 blow‐off valve (BOV). Made from lightweight 6071 and 7075 billet aluminium, the 64mm unit is satin black anodised to be aesthetically pleasing yet functional while offering long‐lasting protection from the elements.
PTE’s new BOV features a Kevlar‐reinforced silicon rolling diaphragm for quick response and a hard‐coat anodised valve stem for enhanced durability. The PB64 also has a CFD designed valve and valve body for the highest flow even at low lift, while the attached O‐ring seal prevents leakage. PTE’s PB64 BOV also utilises an industry‐first proprietary wave spring for added weight savings while still holding the valve closed under high vacuum idling. Designed to release back-up pressure created when the throttle is closed via a spring‐loaded valve diaphragm assembly, PTE’s PB64 BOV is a key component for preventing potentially harmful compressor surge back into the turbocharger to reduce wear on both the turbo and engine.
Precision’s PB64 blow‐off valve is generally compatible with most aftermarket manual and electronic boost controllers on the market, and comes with a manufacturer’s warranty for a period of 12 months or 12,000 miles.
