Technical description

The DUNGS double solenoid valve DMV
integrates two solenoid valves in one

compact tting.

-

Automatic shut-o valves as per DIN EN 161
Class A Group 2.

- Two A valves in one housing

- Double seat valves

- High ow rates

- Max. operating pressure up to 0.5 bar
(50 kPa)

- Fast closing

- Fast opening

(DMV/11 eco, DMV-D/11 eco)

- Adjustable main volume (DMV-D/11 eco,
DMV-DLE/11 eco)

- DC solenoid

- Low electric power consumption through
power switching

-

Mountable closed position signal contact

- Compact, light-weight

Application

Double solenoid valves are used where two

single valves were mounted previously. In

connection with DUNGS gas regulators and

additional components, a wide variety of
regulating tasks can be performed.
It does not contain any non-ferrous metals,
suitable for gases of up to max. 0.1 vol.%

H2S, dry. Suitable for gases of families 1, 2,

3 and other neutral gaseous media.

Approvals

EC type testing certicate as per:

• EC-Gas Appliances Regulation

• EC-Pressure Equipment Directive
