Motorised Butterfly Valve
DMK
Nominal Diameter Rp 3/4 - Rp 2

Technical description
The DUNGS DMK motorised butterfly valve is an actuator without zero shut-off as per DIN 3394, Sheet 2. Input-side male thread and output-side female thread enable a space-saving assembly directly on DUNGS multiple actuators, solenoid valves and other actuators:
- Max. operating pressure: 500 mbar (50 kPa)
- Max. differential pressure: 100 mbar (10 kPa)
- Group R0 as per DIN 3394, Sheet 2.
- Application-specific throat diameter selection of throttle valves
- Standard actuator drives: DMA...P..., DMA...Q... other drives supplied on request
- Reduced installation length by combination of female and male threads
- Functional, rugged and maintenance-free
- Low weight

Application
The DUNGS DMK motorised butterfly valve is used for regulating the gas supply on gas burners and gas equipment.
The motorised butterfly valve can be used for gases of families 1, 2, 3 and other neutral gaseous media.
Does not contain any non-ferrous metals, suitable for gases of up to max. 0.1 vol.% H₂S, dry

Approval
