1. General In addition to this leaflet 219.20 concerning "Operation and Maintenance, Spare Parts" of the pressure reducing valve D 119a (RMG 219), the brochure 219.00 gives full information about all relevant technical data, description of function, the available versions, and dimensions. The RMG brochure "General operating instructions for gas pressure regulators and safety devices" will be useful to fit the regulator into the line, put it into service and find faults that might disturb its operation. Please also check if the construction, set-up, supervision and maintenance of gas pressure regulating stations may be subject to special national regulations. These technical rules should be observed strictly (Within Germany observe the DVGW worksheets G 490, G 491, G 495). The frequency of periodical maintenance of gas pressure regulators and other components of the regulating line is strongly dependant on the prevailing service conditions, the type and composition of the gaseous medium, the ambient temperature and on dust and dirt withing the pipe system. We therefore abstain from imposing any fixed intervals and would rather advise testing out the necessary maintenance intervals, starting with short gaps (i.e. quarter of a year) for maintenance dismantling, and then increasing the intervals to a maximum of 2 years, if no defects within the spare parts show up. For maintenance all parts are to be cleaned and subjected to a thorough visual inspection. Complete dismantling together with visual inspection should not be omitted when the course of operation or performance tests have shown lack of accuracy. Particular care should be given to the checking of sealings and diaphragms, as well as the closing spring and all movable parts. Damaged parts should be replaced by new ones.

Note!

We recommend to keep all parts marked "EV" in stock for maintenance availability.

1.1 Appointed personell Experts Thanks to his technical training, his practical work and his experience, the expert has sufficient knowledge in the field of maintaining complete gas facilities as well as the single devices with their constructional elements and sub-groups. He must be acquainted with the purpose and the tasks of gas pressure regulating facilities, with the relevant laws, guidelines and general technical rules, and must also be capable of deciding and acting on his own. Qualified employee The qualified employee must posess special, proven knowledge for the certain task he is about to perform. He is acquainted with the general rules and regulations, and it is guaranteed that he can carry out tasks correctly when ordered to do so.

2. Special Operating Instructions Setpoint alterations Ton increase the setpoint turn the setpoint adjusting screw to the right. After alteration of the setpoint secuere the adjusting screw with the ring-nut (36, 93, 214) or the screw (80.5, 180.5). Setpoint alterations for the integrated safety relief valve are not possible. The following fixed values are given: - approx. 5 bar for diaphragm assembly M, N, G, GS, F - approx. 10 bar for diaphragm assembly V

3. Special Maintenance instructions • The connection between the lever and the lever yoke must be at a right angle: turn the diaphragm to the left and the right, and then place the diaphragm in the middle between the two stop positions.
