... providing all components you
need for reliability in gas supply

1. General
Our leaflet 610.00 gives full information with technical data , different versions and dimensions of the pilot
RMG 610 (RS 10d).
Our brochure "General Operating Instructions for Gas Pressure Regulators and Safety Devices" will be
useful to fit the valve into the line, put it into service and find faults that might disturb its operation.
The construction, set-up, supervision and maintenance of gas pressure regulating stations are subject to
special technical rules which should be strictly observed, in particular those given by the DVGW Worksheets
G 490, G 491, and G 495.
The frequency of periodical maintenance to be foreseen for the safety shut-off valve RMG 711 should be
determined according to the prevailing service conditions and the type and composition of the gaseous
medium. We, therefore, abstain from imposing any fixed intervals and would rather refer you to the recommen-
dations given by the DVGW Worksheet G 495.
For maintenance all parts are to be cleaned and subjected to a thorough visual inspection. A visual inspection
should not be omitted when the course of operation or performance tests have shown lack of response
accuracy. Particular care should be given to the checking of sealings and diaphragms, as well as of all carrying
and movable parts, engagement and release systems of the tripping and measuring devices and of closing springs.
Damaged parts should be replaced by new ones.
The item numbers referred to in the maintenance instructions are identical with those of the spare parts drawings and
spare parts lists.
We recommend to keep all parts that are specially marked in the spare parts lists in stock for prompt maintenance
availability.

2. Special Operation Instructions
2.1 Adjustment of the auxiliary pressure
The height of the adjusted auxiliary pressure influences the regulating procedure of the device.
To obtain a high precision of regulation, which is connected to a smaller closing pressure, an auxiliary pressure should be
adjusted as high as possible in the stabilization of the gas pressure regulation device.
According to the application the following advised values must be appplicated:
fine filter
protection cap

2.2 Adjustment of the discharge valve
The discharge valve is delivered from the plant with the main
adjustment. The necessary rotation of the spindle for this
adjustment is given on the picture situated on the pilot (see
drawing on the right).
By turning the spindle left to the bleed adjustment " - ", it is
possible to adapt the device to special operation instructions
-additionally to change the auxiliary pressure-
f.i. by regulation variations of "pressure picks" after a quick
closing of the stop organ preswitched.

3. Special Maintenance Instructions
3.1 Auxiliary pressure stage (see page 8)
Diaphragm (68)
By dismantling, put the cover (69) off, put the diaphragm (68) on the side of the inlet pressure connection and
hang the diaphragm on the side outside the joint (80).
Sealing cone (81)
To dismantle the sealing cone, the screws (98) must be unscrewed and the complete joint (80)
must be put off. A mark of the sleeve corner (83) on the sealing surface of the sealing cone (81) is normal.
By installing the sealing cone, the position of the lever joint must be controlled after the installation of the joint and
newly adjusted if necessary.
The correct adjustment is given if the lever is manually put out (piston in closing position) and the superior corner of
the lever is parallel to the diaphragm support.
A possible and necessary correction is obtained by underlaying the different thicker sealing rings (51, 85) under the
intermediary piece.
3.2 Control stage - Tool M and N (see p. 6 and 8)
Control rod (16, 76)
The control rod must lightly slide in its conduction. By installing the new parts in the outlet pressure stage the
adjustment measure of the rod must be controlled according to the measurement tool and be corrected if necessary.
The adjustment measure must be put off according to the following drawing.
Adjustment measure for control stage tool N

610.20 p. 6
Beware:
Piston (23)
The piston of the control stage must lightly slide in its conduction.
The measure controls occur for an incorporated control pin (16, 76), that is to say the control rod
(20) is on the piston (23), the sleeve is still closed. The control rod is delivered with an excessive
length and must for this reason be shorted by replacing corresponding to the adjustment measure
and lastly borderless rounded .
