Abstract:
A control valve includes particle and moisture accumulation inhibiting features. The control valve includes a piston that provides for pressure communication to a back cavity through a tortuous path that settles out particle matter carried within the airflow. Moreover, the piston includes drainage openings that direct moisture out of piston and away from the sealing surfaces.
