The invention is directed to a purge valve (100) with an integrated safety function, suitable for an air-drying device. In the purge valve a purge-valve body (102) forms a first exhaust passage (104) for connecting an inlet line (101) to an outlet line (103). A purge-valve piston (108) is arranged inside the purge-valve body to control a flow of exhaust air through the first exhaust passage upon reception of a purge signal (S). The purge-valve piston comprises a through opening (110) being configured to form a second exhaust passage (112) for connecting the inlet line to the outlet line. A valve member (114) is arranged in the through opening and is configured to control a flow of exhaust air through the second exhaust passage (112). The valve member is configured to be actuated by pressurized air when a pressure value in the inlet line exceeds a threshold actuation pressure.
