Blow -Off Valves and Wastegates

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; we believe this is the largest valve available with the highest flow capacity.
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 weld base mounting flange is furnished with each unit. Stainless Steel is available at an additional cost and mild steel is available at no extra cost. Call to order with a stainless or mild steel flange. All blow off valves come with silver finish and 11 psi spring which can give you boost control over 25psi.

Features:
347 Stainless Steel Alloy is used for valve and valve housing.
High temperature silicone Nomex reinforced actuator diaphragm.
17-7 PH Stainless Steel actuator spring gives consistent pressure at high temperature, resists "relaxing" at temperature to 900F (483C).
Nitronic 60 Stainless Steel is used for the valve seat, and valve bushing the same material used in the higher level gates for reliability and longevity.
CNC Machined 304L 12mm thick weld flanges.
Wastegates shipped with air fittings and stainless hardware.

Tial sells the flanges separately from the 38mm wastegate. They are necessary to use it. Don't forget to order flanges (shown, but sold separately) with your wastegate.

All wastegates come with silver finish and 8 psi spring which can give you boost control to 20psi.

Features:
Includes V Band clamps for mounting!
All stainless steel hardware. Includes fittings.
High temp NiCrFe based alloy is used for valve and 347SS valve

housing will offer longer product life compared to competing designs.
High temperature silicone Nomex reinforced actuator diaphragm.
17-7 PH Stainless Steel actuator spring gives consistent pressure at

high temperature, resists "relaxing" at temperature to 900F (483C).
