  • Publication number: 20090007973
    Abstract: A device for regulating the delivery pressure of gases includes a valve unit having at least one valve seat and a respective closure element displaceable along an axis with respect to the valve seat which is controlled by a diaphragm. The device further includes a first spring which acts on the diaphragm in order to subject it to a preselected resilient load. A second spring is selectively activated to exert an additional resilient load on the diaphragm. The device includes a handle associated with the first and second springs in order to impose selectively the desired delivery pressure value, between a minimum value and a maximum value of pre-calibration, the pressure value being proportionally correlated with a predetermined resilient load exerted on the diaphragm.
