Device models
The configuration levels of the controllers HON 670 / HON 671 can be varied in some respects
using individual components.
The following individual components are always part of the device:
▪
Spring adjuster of the pilot spring
▪
Amplifying valve
▪
Comparator stage
▪
Base plate
▪
Pressure unit
The following individual components are installed in some versions of the device:
▪
Comparator stage
▪
Diaphragm measuring unit
▪
Diaphragm assembly with ball guide sleeve
▪
Metal bellows measuring unit
The comparator stage as an individual component is executed in three models with different
designs in dependence on the control range (W
d
) of the controller:
Series
Design for upper response pres-
sure
Control range W
dso
Thread type
[bar]
[psi]
K16: Diaphragm measuring unit
0.8 - 20
11.6 - 290
HON 670
K16: Diaphragm assembly with ball
guide sleeve
10 - 40
145 - 580
Metric, imperial
K18: Metal bellows measuring unit
20 - 90
290 - 1305
Series
Design for lower response pres-
sure
Control range W
dsu
Thread type
[bar]
[psi]
K17: Diaphragm measuring unit
2.0 - 20
29 - 290
HON 671
K17: Diaphragm assembly with ball
guide sleeve
10 - 40
145 - 580
Metric
K19: Metal bellows measuring unit
20 - 90
290 - 1305
The designs that use the imperial system of measurement feature ports that conform to
Anglo-American thread standards and use inches as a unit.
The designs that use the metric system of measurement feature ports that conform to Euro-
pean thread standards and use metric units.
The technical specifications and the spare parts lists and spare parts drawings in the appendix
describe all the models of the HON
670 / HON 671 controllers.
The Maintenance section describes the controller using the example of the models with a
diaphragm measuring unit and a metal bellows measuring unit. It does not explicitly describe
every single version and design.
If you have trouble understanding the information in this documentation, contact the manu-
facturer without fail before starting any work on the device.
