TIAL 002909 F38.9B Wastegate 38mm .9 Bar (13.05 psi) Blue
The MV-S 38mm unit is much more compact than its F38 predecessor - standing only 3.7” in height. The V-Band flanges make installation pain free, the three lower & two upper air ports make connecting pressure sources and boost controllers easy!
- High temp NiCrFe based alloy valve and 316SS valve housing 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 and resists "relaxing" up 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).
- 3 lower ports and two top ports for easy install, no need to rotate the actuator top at all, plugs included for unused ports.
- Ultra compact design fits in very tight spaces.
- V-Band inlet and outlet make install easy, flanges and clamps are in the box!
- Integrated -4 AN water cooling ports that cycle a small amount of coolant through the actuator top to keep the temperatures down in extreme conditions such as road racing. These are leak tested after installation from the factory and can be removed if not utilized.
- Optional valve position sensor available for purchase in a MV-S assembly or in an actuator kit to adapt to standard MV-S. See images below for reference.

2 TiAL -4 AN removable water fittings
MV-S Valve Seat
Inlet V-band clamp & Flange
Outlet V-Band Clamp & Flange
2 TiAL Air Fittings
Plugs for unused air ports

TIAL V-BAND CLAMPS
altTiAL designed V-Band clamps and flanges are manufactured in house.
CNC machined stainless steel clamps and CNC machined flanges ensure a secure and pressure tight fit.
TIAL RACING VALVE STEM
altTiAL's MV-S is equipped with the racing valve stem. The wear coating is resistant to the corrosive effects of lead oxide which is present when running leaded racing fuel.
