The invention discloses an altitude valve which is composed of an upper coupling head, a valve body, a sealing ring, a dust ring, a valve element and a lower coupling head. The upper coupling head (1) is connected with the valve body (2) through a connecting screw rod (10) at the lower end of the upper coupling head (1) and is fixed through screwing of a nut (9), the sealing ring (3) and the dust ring (4) are mounted on the valve body (2), the valve element (5) is mounted on the lower portion of the valve body (2), an air spring intake and exhaust channel (13) is arranged in the valve element (5), and the lower coupling head (6) is mounted on the lower portion of the valve element (5). A valve body air chamber air inlet (7) is formed in the upper end of a valve body air chamber (11) and is connected with an air source outside the valve body (2); a valve element air inlet (8) is formed in one end of the valve element (5) and is connected with the air spring intake and exhaust channel (13) in the middle of the valve element (5), and a valve element hole (12) is formed in the valve element body above the air spring intake and exhaust channel (13). Through reciprocating linear movement of the valve element in the valve body, the functions of inflation, air maintaining, exhausting and the like of an air spring in an air suspension system are achieved, and adjustment is avoided after installation.
