Installing the gas pressure regulator
For actuator assemblies with nominal inlet sizes of DN 25 to DN 100 and an expander at the
gas outlet, the manufacturer recommends adding an adapter, immediately upstream of the
gas pressure regulator, to the gas regulating line. If there is a device fault, or in order to check
the device’s state, the body segment with the expander and integrated noise reduction can
remain in the regulating line in this case while the adapter and the remaining gas pressure
regulator sub-assemblies are removed from the regulating line one after the other.
Prepare the following materials:
▪
Flange gaskets
Number, design, and size as per flange connections
▪
Fasteners (screws, bolts, studs, washers, nuts)
The number, size, and thread type are based on the flange design and size
▪
Adapter (optional)
Length as per
Technical specifications
(see page 22), version as per gas regulating line
Assess the installation situation.
