Important:
The setpoint depends on the diaphragm position and must be adjusted according to the assembly position.
The configuration can be sealed using the lateral hole in the setting screw. Factory-sealed devices are set to the
specified pressure.
Assembly must be performed on both sides (p
1
, primary side and p
2
, secondary side) within non-turbulent flow. To that
end:
- Straight inlet piping of 5 x DN on the primary side and
- Straight outlet piping of 10 x DN on the secondary side is recommended
Furthermore, it is recommended that you install one shut-off valve each before and after the pressure regulator to
simplify any maintenance work. Furthermore, a suitable filter must be installed before the pressure regulator in case of
dirty gases or if there is a hazard of solid particles.
Avoid pressure shocks after assembly and always open shut-off valves slowly!
