The Dungs GB Valve is a multifunctional Gas Control with
combined regulator and safety shutoff valves.
The pressure regulator includes a servo regulator to regulate
pressure fluctuations in the mains supply. This ensures a
precise volume flow and constant injector pressure.
To shut down the pressure regulator turn the setting device
25 times clockwise until a soft click can be heard.
