Service and repair
• All work on the regulator is to carry out only
in the pressure-free condition. The safety
regulations, in particular the UVV’s, as well
as the DVGW papers G 490, G 491 and G
495 are to be considered:
• Valves on the upstream- and downstream
side are to closed.
• The pressure must be reduced by the relief
valve on the outlet side, up to zero level
Caution:
When disassembling the regu-
lator, the loading spring is to
release before!

Commissioning SSV-II (upper and lower shut-off)
Cover cap (b) unscrew and onto valve rod (a) screw. Valve rod slowly pull out, until outlet pres-
sure adjusts itself in the controller and the lever system of the SSV’s engages and the valve
rod in open position remains. It’s only possible, if the outlet pressure pd of the regulator
smaller then the shut-off pressure pdso and bigger than the shut-off pressure pdsu!
Be sure to screw on cap (b).
