Tial QR Blow Off Valve


Price: $245.00

QR is the more compact recirculating BOV. Optional 1.0" or 1.34" reciruclation port, uses the standard TiAL V-band flange and can be converted into a standard Q BOV by swapping the bottom piece.


- For use on turbo-charged and super-charged applications (Paxton, Vortec, etc.). The body and all internal components are CNC-machined from 6061 aluminum alloy. It features a large 1.98 in (50.5mm) valve.
- The V-Band design aluminum mounting clamp gives a very clean and unique appearance. The clamp is anodized and uses Stainless Steel hardware for a long lasting, corrosion-free appearance.
- The valve seal utilizes a Viton O-ring that is clamped in place to prevent the possibility of sticking to the seat and pulling out. The valve stem and guide are Teflon-lubricated, hard anodize-coated for wear resistance.
- The Blow Off Valve also comes with our own machined aluminum banjo-type air fitting and bolt, with over sized 10mm hose barb for quick actuator response. The actuator has a high temp silicone Nomex-reinforced diaphragm for long life.
- An aluminum or mild steel weld base mounting flange is furnished with each unit. Stainless Steel is available at an additional cost. The use of 6061 aluminum allows the housing to be anodized with a selection of colors.
- This new more compact recirculating bov is set up to accept two different types of retun fittings - 1" for Bosch style BPV's and 1.34" for DSM and Evo type valves. Please specify size at time of order.
- A nice feature of this BOV is that you can swap bottom with the bottom of a Q BOV to make it a fully vent to atmosphere BOV.
