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.
