This MV-S-A & MV-S-AR 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 & MV-S- AR has a 38mm valve but also has heat isolating and  dissipation fins that separate the casting from the actuator top.  Born into the world of Motorsport this waste-gate can handle the harshest of conditions and give the confidence of 100% performance.  It is the choice waste-gate of many WRC and Grand-am teams.

SPECIFICATIONS

• 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
• 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 utilised
• Five heat sinks raise the actuator top away from the casting to dissipate heat when water cooling can not be used
• Designed for Motorsport/Road Racing

WHATS IN THE BOX

Included with every TiAL MV-S-A:

• MV-S-A Assembly 
• 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 
• Extra actuator springs

WATER COOLED ACTUATOR TOP

• Patent pending water cooling 
• Two -4AN water ports 
• Coolant passes through actuator bottom and has very little affect on cooling system as a whole

TIAL V-BAND CLAMPS

TiAL 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

TiAL's MV-S-A 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.
