Ford Racing 16-18 Focus RS Uprated Turbo Recirculation Valve
The Ford Performance Parts uprated turbo recirculation valve (TRV) is a direct replacement for the OE component. Machined from solid aluminum with a piston-type design (compared to the OE diaphragm) the more robust design and material are suitable for vehicles in an 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. With increased boost pressure, compressor-out temperatures can exceed the safe operating limit of the OE valve. The Ford Performance Focus RS TRV is engineered to withstand much greater temperatures while maintaining performance, making it an essential upgrade for cars running increased boost pressure.
