Design and Operation closing spring throttling diaphragm expansion piece inlet pressure loading pressure valve seat valve sleeve closing spring load limiting pressure outlet pressure atmosphere The compact device RMG 0 MonitAc consists of two operating units, the first one is responsible for the active control of the outlet pressure, and the second unit for the monitor tasks: The pilot of the active unit (pilot-series RMG 0 or RMG 0a) compares the actual value of the outlet pressure with the setpoint value and drives the movements of the throttling diaphragm. The gas flow is controlled by the rolling movement of the diaphragm on the expansion piece. Thus the outlet pressure remains constant and independant from variations of the inlet pressure and the flow rate. For zero flow, the closing spring presses the diaphragm against the sealing edge. The outlet pressure is additionally checked by the monitor unit. As the setpoint of this unit is set to an higher value as the controlled pressure of the active unit, the monitor device is normally completely open. In case of failure, the active unit opens according to the»fail-open«principle, and the outlet pressure rises. The setpoint value of the monitor unit is reached and this unit starts to control the outlet pressure. A valve sleeve which is controlled by the corresponding pilot RMG 0 is used for the gas flow regulation within the monitor unit. The closing force for zero flow is produced by the closing spring, which presses the sleeve against the valve seat.

At zero flow the outlet pressure rises up to the closing pressure limit of the monitor unit.
