General information
All persons involved with the assembly, operation and / or maintenance of the pressure reducer RMG 213 must
read and understand all of the following documents:
- Technical product information 213.00 – this RMG document contains the technical data and dimensions of
the equipment as well as instructions concerning construction and mode of operation.
- General operating manual for gas pressure regulators and safety devices – this RMG document contains
information on assembly and operation as well as general information on troubleshooting.
- Operating and maintenance instructions, spare parts 213.20 – this RMG document contains more
detailed information on assembly and operation of the pressure reducer RMG 213.
There are national laws and regulations for all sorts of jobs on gas pressure governors, from planning to
maintenance. Be sure to comply. (In Germany, for instance, DVGW work sheets G 600, G 459/II, G 491
and G 495.)
Inspection and maintenance intervals depend mostly on operating conditions and the nature and properties of
the gas. There are no general rules or recommendations for intervals. For Germany, we recommend to
consider maintenance intervals as stated in DVGW work sheet G 495 in a first instance. However, in the
mid-term, intervals must be adapted to the requirements of each specific equipment.
During maintenance, components must be cleaned and then checked thoroughly. This is necessary even if
there have not been any unusual observations during operation and / or functional testing. Checks must focus,
in particular, on diaphragms and seals and all movable parts and their respective bearings. Any and all
defective parts must be replaced with new ones. The same applies to O rings removed during disassembly.
Do not use any spare / wear parts and / or oils & lubricants not specifically recommended in the RMG
operating and maintenance instructions for spare parts. In the event spare / wear parts and / or lubricants &
oils other than those specifically recommended are used, RMG shall not be held liable for any defects and / or
consecutive damages attributable to such use of illegal parts, lubricants, oils etc.
Item numbers mentioned in the specific operating and maintenance instructions correspond with the numbers
in the spare parts lists and drawings.
Some parts in the lists and drawings are marked with a letter "W". We recommend to always have a reserve of
those parts in stock for maintenance purposes. Those spare parts are put together in another separate list at
the end of the spare parts list.
