1. General

Our leaflet 832.00 gives full information with technical data , different versions and dimensions of the

safety relief valve RMG 832.

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 relief valve RMG 832 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.

3. Special Maintenance Operations

3.1 Torque

Sealing ring (8)

• Plastic material sealing rings must be principally renewed for each maintenance.

Piston (23)

• The breathing of the spring stage is garantied through the capillary tube which is set in the piston;

the capillary piercing must have a free straight passage.

Measuring diaphragm (24)

• By installing the measuring diaphragm, the setpoint spring (29) must be turned at a certain distance in the spring

body unit (14); the internal diaphragm release comes to the same height with the external release at the same

level as the sleeve (27).
