2.1 Intended use
The HON 380 direct-acting gas pressure regulator must be used and operated
exclusively with a compatible controller made by Honeywell. The gas pressure reg-
ulator is to be used in combination with a controller to provide a safety-shut off
function in a regulating line.
Depending on the type, the gas pressure regulator can be used to maintain the
outlet pressure of a gas constant within the regulating line, regardless of the influ-
ence of disturbance variables such as pressure changes and/or changes in con-
sumption.
As a gas pressure regulator, it can be used in transfer stations used in gas trans-
portation networks, as well as in power plants and industrial facilities. Gas pres-
sure regulator HON 380 with controller HON 673/HON674 is suitable for use
with natural gas or dry, non-aggressive industrial gases.
Note: The utilization limits of the device with regard to the medium, operating
pressure and operating temperature can be gathered from the type plate at-
tached on the device or the technical specifications.
The use under different operating conditions must be coordinated in consultation
with the manufacturer.
Please observe the following limitations of use:
Do not use the device for any media other than those mentioned in the in-
tended use or those discussed with and approved by the manufacturer.
Do not use the device in any installation position other than the one docu-
mented in this user manual.
Do not use the device against the direction of flow specified on the device
and in the user manual.
When replacing defective parts, only use original spare parts or manufac-
turer-approved standard parts.
Do not attempt to modify or remodel the device on your own.

400 to 5200 mbar K2b: Diaphragm measuring unit
Control range Wdsu Design for lower response pressure
10 to 300 mbar K1a: Diaphragm measuring unit
60 to 400 mbar K2b: Diaphragm measuring unit
The comparator stage as an individual component is executed in three models
with different designs in dependence on the control range (Wd) of the controller:

The technical specifications and the Maintenance section, as well as the spare
parts lists and spare parts drawings in the appendix, describe all the gas pressure
regulator versions and all the models corresponding to the standard for this de-
vice type. Special-purpose versions are identified with “SO” in the inspection cer-
tificate, which is included with the gas pressure regulator.
However, other versions and models will be covered specifically as well when there
are important differences that need to be pointed out.
If you have trouble understanding the information in this documentation, contact
the manufacturer without fail before starting any work on the device.
2.3 Labels/Markings
Illegible information on the device poses a risk of injury due to resulting erro-
neous operation, use, or installation.
Labels, as well as inscriptions and stamping on the device, can eventually be-
come soiled or otherwise unrecognizable to such an extent that users will not be
warned effectively of hazards and may be unable to follow required operating in-
structions. This will pose a risk of injury.
Make sure to always keep all relevant labels in good condition so that they will
be easily legible.
Immediately replace damaged and missing labels.
The labels and markings of the gas pressure regulator can be found here:

4 Body nominal size
5 Arrow indicating the direction of flow
For the location of the nameplates, as well as a detailed list of the information on
them and what it means, please refer to:
Identifying the device (see page 10)
Small labels must be used to color-code and explicitly name the gas pressure reg-
ulator’s connection lines (measuring lines and operating lines) based on what the
lines are intended for and their minimum nominal size.
