It’s 2026 and the all new Version 4 QSV is available, refined blade design and even greater water flow make our valve more reliable that ever under extreme circumstances!!!

Do you have a twin scroll turbo? and would you like faster spool up and higher top end power? I think we would all answer yes to the latter……

Now 13 years of development has lead us to this latest QSV design which can be used on many different applications including petrol and diesel high bhp options. The valve body is watercooled to allow more stable operation and durability. The one piece CNC machined valve blade and shaft is a stainless steel construction and strongest in class.

New Features 

• Higher grade stainless steel shaft blade
• Upgraded bushing material
• Larger internal cooling passageways

Description

This valve deflects gas rather than simply blocking off one port allowing even better spool up than our previous design and less hot spots on the material. Replacing bronze bushing and a labyrinth gas seal. Supplied with actuator (opening pressure under 1.0 bar).

This system can also be used on twin scroll manifolds due to the chamfered recess under the divider
