Tial MVR Wastegate

The MV-R 44mm wastegate is more compact than any current 44 or 46mm wastegate on the market. You get two top air ports and three bottom air ports for easy install. This unit is a direct bolt on for our V44. The MV-R has an optional extreme high temp casting available for Motorsport applications

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.
• 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.
• Extreme high temp casting available for Motorsport applications
• Optional valve position sensor available for purchase in a MV-R assembly or in an actuator kit to adapt to standard MV-R.  See images below for reference.

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.
