TiAL 003888 MV-S 38mm External Wastegate with V-Band Flanges

The TiAL MV-S 38mm External Wastegate is an ultra-compact, high-performance boost control solution engineered for turbocharged applications where space is at a premium. Standing just 3.7" tall, the MV-S is significantly more compact than its F38 predecessor and features V-Band inlet and outlet connections for straightforward installation.

The MV-S is built from premium high-temperature alloys throughout. The valve is constructed from a high-temp NiCrFe-based alloy while the valve housing is 347 stainless steel, offering superior corrosion, wear, and galling resistance. The valve seat and bushing use Nitronic 60 stainless steel, and all hardware is stainless steel. The actuator housing is CNC machined from lightweight billet aluminum and is available in color-anodized finishes.

Key Features:

• Ultra-compact design at only 3.7" tall — ideal for tight engine bays and twin-scroll dual-wastegate setups
• V-Band inlet and outlet connections — mating flanges and clamps included
• Three lower ports and two upper ports for flexible boost controller and pressure source routing — no need to rotate the actuator top
• Plugs included for all unused air ports
• High-temperature silicone Nomex-reinforced actuator diaphragm
• 17-7 PH stainless steel actuator spring resists relaxation at temperatures up to 900°F (483°C)
• Nitronic 60 stainless steel valve seat and valve bushing
• 304L stainless steel mating weld flanges
• Integrated -4AN water cooling ports for extreme-duty applications such as road racing and rotary engines
• Color-anodized aluminum actuator available in Silver, Red, Blue, Purple, and Black
• Includes all MV-S actuator springs — supports boost pressures from 4.35 psi (0.3 bar) up to 24.66 psi (1.7 bar)
