PB50 50mm Blow Off Valve by Precision Turbo & Engine (PTE)

The PTE 50mm Blow Off Valve is designed to be a direct fit replacement for other units on the market. As an added bonus, the unit is warranted to be free from manufacturers defect for a period of 12 months or 12,000 miles.

Made from lightweight 6061 and 7075 billet aluminum, PTE's 50mm unit is satin black anodized to be aesthetically pleasing yet functional while offering long-lasting protection from the elements.

It features a Kevlar-reinforced silicon rolling diaphragm for quick response and a hard-coat anodized valve stem for enhanced durability. The 50mm BOV 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.

Furthermore, PTE's 50mm BOV also utilizes an innovative and 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 50mm BOV is a key component for preventing potentially harmful compressor surge back into the turbocharger to reduce wear on both the turbo and engine.

Packaged with a weld-on aluminum mounting flange, spring adjustment screw, and two top ports for the ultimate in versatility and adjustability, the high-performance 50mm BOV is generally compatible with most aftermarket manual and electronic boost controllers on the market today.
