1. General information
All persons involved with the assembly, operation and/or maintenance of RMG 530 volume control valves must read and
understand all of the following documents:
–Technical product information brochure 530-E-WG- it contains the technical data and dimensions of the equipment as well as
instructions concerning set-up 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 530.24- this document contains more detailed information on assembly
and operation of RMG volume control valves 530-E-WG.
There are national laws and regulations for all sorts of jobs on gas pressure regulators, 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 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.
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 you 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.
1.1 Safety information
In this manual, safety information is highlighted by means of the following titles and eye catchers:

530.24 S.04
2. Specific maintenance instructions
Under normal circumstances, maintenance jobs may be limited to the sealing elements of the drive shaft and actuator
(zero shut-off) and the threads of the spindle and mitre gear.
2.1 Disassembling and replacing seals
Use the electrical actuator to move the valve sleeve to the UP position. (Limit switch UP switches off.)
Remove screws/bolts (37) to dismount the rotary drive + cap (5).
Check the thread and feather key groove of spindle (23): Worn?
- The sides of the thread must be smooth– no score marks.
- The unit consisting of the spindle+ rotary drive must not show any axial play.
- The spindle must screw easily into the rotary drive.
- Lubricate the spindle (23), internal thread of the rotary drive (15), feather key (24) and key-feather
groove generously.
Mark the position of the drive shaft (3) with a view to actuator (16) and in relation to the feather key (2)
and position of plate (53). (Important during re-assembly.)

shaft (3) and plate (53) must match.
Note
Loosen the cheese head screw in adjusting nut (4) and remove the nut.
Remove the cheese head screws (7).
Remove the plate (52) from housing (16) by screwing in two 2 M10 eye bolts.
After you removed the cheese head screws (56), pull bush (58) out of plate (53).
Replace the seal (54). Consider the proper position when fitting: The coil spring must point in the direction of the pressure side.
Remove the device from the system and place it on its inlet flange. Remove the cheese head screws (29) and pull
out the outlet part (34) towards the top.
Discard the O rings (28+ 45) and put in new ones.
Loosen the cheese head screw in adjusting nut (41) and remove the nut. Remove the valve sleeve (40). Use two M8 eye bolts to
pull it out of the device .
Loosen screws/bolts (47) and remove ring segment (32). Discard seal elements (43+ 44) and place new ones.
Remove release sleeve (38). Use two M6 eye bolts to pull it out of the device . Discard the O ring (64), compensation ring (62),
guide-ring (61) and seal (63) cpl. w/support ring (60). Use new ones. Clean the grease chamber (48) and fill with new lubricant
(48).
Loosen the cheese head screws (25) in bush2 (26), and pull out bush2. Remove and clean the feather key (24).
Screw out the cheese head screws (20) and pull out bush1 (22). Remove the spindle (23).
2.2 Checking components, assembly
Clean ALL the components. Find and grease all components mentioned in lubricant table 2.4 before you put them back in.
Grease ALL screws+ bolts before you put them back in. Consult table 2.5 for tightening torques MA.
Insert spindle (23) into rotary drive (15). Screw down bush1 (22) onto rotary drive. Place feather key (24) into the groove
on spindle (23). Place bush2 (26) on top. Use the cheese head screws (25) and lock washers (27) to tighten everything.
