The invention belongs to the field of mechanical assembly technical, and particularly relates to a device for testing open-close of a media self-driven valve. In the invention, a test flange is fixedly connected to the main valve body through a storage fastener; a sealing gasket is arranged between the main valve body and the test flange; a cooperating passage is arranged in the main valve body and the test flange; an outer wall of the test flange is connected to a metal pipe; a manual valve 2 is arranged at the metal pipe; the metal pipe is connected to the internal passage of the test flange; and the internal passage of the test flange is connected to a manual valve, a quick joint, compressed air hose, a quick connector, and a manual valve three through the metal pipe. According to the device for testing open-close of the media self-driven valve, the stable supply of compressed air can be ensured, personnel and time investment are reduced, and safety risk of the compressed air hose to the injured person is
