An expiration valve for an automatic respirator comprises a main body which is separable into a valve body and a diaphragm and a container which engages to a tube for supplying control pressure to one side of the diaphragm. A means for controlling such an expiration valve comprises a means for generating pressure for opening and closing the valve, a means for controlling this pressure, a pressure detector means, an exhaust means and a control means so that the valve can be electronically controlled for both the valve opening/closing functions and for the positive end expiratory pressure function.
