Precision Turbo PTE PB64 Race Blow Off Valve 64 mm
High quality premium 64 mm open BOV with aluminum weld-on flange
Precision Turbo open blow off valve comes with aluminum flange and connection fittings
Made of lightweight 6061 and 7075 aluminum, PTE's 64mm BOV is anodized matte black to be aesthetically pleasing yet functional and provide long-lasting protection from the elements. It features a Kevlar reinforced silicone diaphragm for quick response and a hard anodized valve stem for improved durability. The PB64 also features a CFD designed valve and valve body for highest flow even at low lift, while the attached O-ring seal prevents leaks. In addition, PTE's PB64 BOV features an innovative and industry-unique wave spring that provides additional weight savings and keeps the valve closed at idle, even at high vacuum.
PTE's PB64 BOV is designed to release the back pressure created when the throttle valve closes via a spring-loaded valve-diaphragm assembly. It is a key component in preventing potentially damaging volume blowback back into the compressor to reduce wear on both the turbo and the engine. The PB64 comes with an aluminum weld-on flange, spring adjustment screw and two top ports.
