RMG 330, DN 25 and DN 50
This gas pressure regulator was designed to keep the out-let pressure of a gaseous medium constant in the mains and independent of disturbing influences like inlet pressure and/or flowrate changes.
The RMG 330 consists of a main valve body and the units "regulator" and "safety shut-off valve" (SSV measuring unit). Both units can easily be removed from the body by loosening the connection screws. This advantage of easy maintenance offers the following possibilities:For regular maintenance the parts of the regulator and shut-off control elements can be taken out of the body and easily subjected to a visual inspection. In case of failure the
regulator and shut-off units can be replaced by spare units, and the repair works can be carried out in the workshop without having to shut down the system.
A compensating diaphragm ensures pressure balance at the control element of the regulator main valve which can be equipped with orifices of various sizes. The regulating assembly can be equipped with a leakage relief valve (SBV) as an optimal feature.
The outlet pressure to be controlled is fed to the diaphragm assembly via the measuring line.

RMG 330, DN 80 and DN 100
The measuring diaphragm takes up the actually prevailing outlet pressure and compares it to the setpoint value pre-adjusted and given by the force of the setpoint spring. Any deviation of the outlet pressure from the setpoint will cause a corresponding change of the valve stem position, and the resulting change in flow rate will re-adjust the outlet pressu-re to the setpoint.
The regulator gives tight shut-off on zero flow.
The control element of the safety shut-off valve (SSV) in-stalled in the inlet side of the body cuts off the gas flow if the outlet pressure in the main rises above or falls below preset limits.
The SSV measuring diaphragm and switching bush then moves into the release position, and the ball mechanism sets the valve stem free to close the SSV valve. The safety shut-off valve can be re-opened by hand only, after the outlet pressure at the measuring point has been restored to a value below the re-engagement differential (after a preceeding overpressure release) or to a value above the re-engagement differential (after a preceeding underpressure release).
