ABSTRACT:
A purge valve for use with an air drying system is provided. The valve includes a housing or body, a piston disposed within the body, and a valve in communication with the piston. The respective geometries of the piston body and the valve define a circumferential cavity between and around the piston body and the valve. A sealing means is disposed within the circumferential cavity for forming a seal between the valve and the body. A plurality of guide members attached to or formed integrally with the valve provide positional stability to the valve within the body and provide enhanced airflow in, through, and around the valve.
