Abstract
A pressure regulating device for gaseous and liquid fluids contains a pressure regulator with an inlet and an outlet and a pressure space between them. The pressure in that space is regulated by a shiftable main valve. An actual pressure value chamber is connected with the pressure space. A set value or desired value chamber communicates through a diaphragm with the actual value chamber. The diaphragm is movable to move the valve body for adjusting the actual pressure in the pressure space to the desired pressure in the desired value chamber. An electromagnetic set-point adjuster adjusts the pressure in the desired value chamber. The adjuster includes a set-value transducer, with an actual value sensor which is exposed to the pressure in the pressure space, and the transducer produces an electric signal corresponding to that pressure. That signal is compared with a set-value signal for establishing a signal which controls the electromagnetic set-point adjuster to set the desired value for the pressure in the desired value chamber which, in turn, will set the pressure in the actual pressure value chamber and therefore the pressure in the pressure space.
