- Alpha Q is the first ever recirculating blow-off-valve offered by TiAL. This unique 50mm BOV flows 6% more than the current vent-to-atmosphere. - 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 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. - An aluminum or mild steel weld base mounting flange is furnished with each unit. Stainless Steel is available at an additional cost. - Made in the USA. Included with every Tial Alpha Q BOV:

  • AlphaQ BOV Assembly
  • TiAL V-Band Clamp
  • V-Band Weld Flange
  • High Pressure O-Ring
  • TiAL Air Fitting
