The membrane valve body includes at least two layers of chambers which is configured in the valve body, and at the interior of each said chamber a duct is mounted, out of which covered with the bigger air coupling. A membrane is arranged to separate the chamber from the duct, furthermore, the membrane acts as a valve gate controlling the communication between the duct and the air coupling, in which: a connection air tube is configured at the air couplings directly between the upper and lower chamber. The upper membrane is entirely sealed, when the magnetic valve starts, the upper and lower membrane valve gates may switch on or off simultaneously, to reduce delay phenomena generated during the operation, and effectively abbreviate the mechanism movement time, and firm the valve gate to switch on or off.
