Uprated Re-Circulating Valve [Mk3 Focus RS]

This part does not affect the base vehicle warranty.

The mountune uprated turbo re-circulating valve (TRV) is a direct replacement for the OE component.

Machined from solid aluminium with a piston-type design (compared to the OE diaphragm) the more robust design and material are suitable for vehicles in advanced state of tune.

A diaphragm-design recirculation valve could function less effectively when the pressure differential across the turbocharger compressor housing is increased above the original operating conditions. This can cause the valve to open prematurely, leading to possible turbocharger damage due to increased turbo shaft speed.

During development, with increased boost pressure, compressor-out temperatures were seen to exceed the safe operating limit of the OE valve. The mountune Mk3 Focus RS TRV is engineered to withstand much greater temperatures whilst maintaining performance, making it an essential upgrade for cars running increased boost pressure.


  • Mounts directly on OE turbocharger
  • Easy installation
  • Suitable for vehicles running increased boost pressure
  • Higher safe operating temperature
  • Superior piston type design
  • Hard anodised for durability
