2 Application, Charac-
teristics
2.1 Application
Gas pressure regulator (GDR), direct-acting (operating without auxiliary power), for systems acc. to
DVGW work sheets G 491 (A) and G 600 (A) (TRGI)
Particularly suitable for dynamic regulation sections (e.g. natural gas supply systems,
low flow regulators, burner circuits, gas motor operation)
Can be used for the gases defined in DVGW work sheets G 260 / G 262 and neutral non-aggressive gases.
(other gases on request)
2.2 Characteristics
• Integral pressure-tight model (IS)
• Diaphragm assembly with internal or external measuring line
• Open-air model
3 Avoidance of Foreseeable Misuse
2.3 Types of Models (Options)
• The regulators must not be used to control liquids.
• The regulators must not be used in temperature ranges below -20 °C or above 60 °C
• The regulators must not be used for pressure ranges higher than the pressure “PS“ indicated on the nameplate.
• The regulators may only be used for the gases specified under item 2.1 Application in these operating
instructions.
Other gases, such as oxygen or hydrogen, must be explicitly stated on the nameplate.
Please consult the manufacturer before use.
• The regulators must not be used in high-temperature areas (HTB) without an upstream HTB fuse.
• Oxygen model (p
u
≤ 10 bar)
• With BV breather valve
• With RSD throttle valve
• Hydrogen version
