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 regulator,
the loading spring is to release be-
fore!
Commissioning SSV-II
Cover cap (b) unscrew and onto valve rod (a) screw . Valve rod slowly pull out, until outlet pressure 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) .
Commissioning SSV 033 / SSV-I
Cover cap (b) unscrew and onto valve rod (a) screw . Valve rod slowly pull out, until outlet pressure 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.
Be sure to screw on cap (b) .
