A boost device diverter control valve (1) has a body (2) with an inlet port (3) extending between a distal end (4) adapted to be disposed in communication with an intake of the boost device and a proximal end (5) in or adjacent the body (2). A piston chamber (6) is in communication with the proximal end (5) of the body inlet port (3) and includes a piston chamber inlet port (7). Piston chamber (6) has a piston (8) disposed therein and movable between a closed position substantially sealing the inlet port distal end (4) and an open position allowing communication between the body inlet port (4) and the piston chamber (6) where the piston (8) is resiliently biased towards the closed position. A longitudinally extending three-way solenoid valve (15) is in communication with chamber (6) and has a solenoid inlet (18) in communication with the body inlet port (3) via a body channel (19) extending between them where the solenoid (18) has a first solenoid output allowing communication between the piston chamber inlet port (7) and the piston chamber (6) and a second solenoid output allowing communication between the piston chamber (6) and a body outlet port (22). A one-way valve (24) disposed in the body outlet port (22) allowing flow therefrom.
