The RMG 408 gas pressure regulator consists of the actuator board, the working “command unit” and the “SAV” toggle. The control unit is composed of an actuator and an actuator and the filter regulator is connected. After the screws are loosened, the working modules can be separated from the actuator shell. This includes a separate maintenance facility. At the measurement location, the starting point for pressure reduction is recorded and fed to the operator via a measuring sequence. The diaphragm in the controller 7 senses the actual value of the output pressure and compares it to the value of the spring force defined (adjustable comparison variable).
