The Tial MVS-A 38mm unit is designed specifically for motorsport applications that can't utilize the water cooling ports on the standard MV-S wastegate. The MV-S-A or "long neck" has the standard 38mm valve but also has five heat fins that separate the casting from the actuator top. Born into the world of Motorsport this wastegate can handle the harshest of conditions and give 100% performance 100% of the time. It is the choice wastegate of many WRC teams.Specifications:
- 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, resist "relaxing" at temperature to 900F (483C).
- Nitronic 60 Stainless Steel is used for the valve seat, and valve bushing.
- All Stainless Steel hardware.
- Mating weld flanges are 304L
- Color anodized aluminum actuator (Silver, Red, Blue, Purple, Black).
