The Centurion pneumatic relay valve for starting systems acts as a high-flow control
valve, enabling efficient and rapid air flow to initiate an engine’s starting process. The
relay valve is crucial for preventing damage to the starter and flywheel by ensuring a
quick engagement and disengagement of the starter motor.
