Gas Solenoid Valve
Dungs MB-DLE 412 B01 S20 Gas Solenoid Valve
The Dungs MB-DLE 412 B01 S20 is a gas solenoid valve in the Dungs programme, rated about DN25 motorised regulating valve for gas trains needing shut-off + modulation. The Dungs MB-DLE 412 B01 S20 combines an automatic shut-off with a motorised regulating stage for controlled gas flow on burner trains. It is used where a Dungs valve must both shut off and modulate gas flow, with the S20 spring and B01 body matched to the duty. The MB-DLE412 is the smaller combined shut-off and motorised regulator, below the 415 in flow class.
Why buyers choose it
- Rated about DN25 motorised regulating valve — matched to gas trains needing shut-off + modulation, not a generic catalogue figure.
- The MB-DLE family is the combined shut-off + regulator that replaces a separate valve and regulator in one body.
- The MB-DLE412 is the smaller combined shut-off and motorised regulator, below the 415 in flow class.
- Stocked by Zhongli Weiye as a compatible Dungs spare, cross-checked against the original part.
- Fitment: Shut-off + motorised regulation
- 3-year warranty on complete units & core components, with pre-dispatch inspection.
- Choose the 412 when the train's duty is modest — the S20 spring and DN25-class body cover the small-duty end of the MB-DLE programme.
- Commissioning stays simple because the 412 reuses the same S20 spring concept used across Dungs' smaller regulating valves.

Applications
Dungs MB-DLE 412 B01 S20 is specified for gas trains needing shut-off + modulation where gas solenoid valve duty must stay stable across load swings.
Plants also fit the MB-DLE 412 B01 S20 to smaller MB-DLE flow class, because its mb-dle 412 b01 s20 control keeps commissioning simple.
For regulated gas-flow burners, the MB-DLE 412 B01 S20 is the Dungs option that The 412 is the smaller MB-DLE handled here, below the 415 in flow class.
Its S20 spring and B01 body suit controlled gas flow on compact burner trains.
On small gas-fired ovens, bakery lines and compact steam boilers, the 412 is the usual pick: its lower flow class matches the burner's gas demand without oversizing the train.
Buyer Questions
Dungs MB-DLE 412 B01 S20 Gas Solenoid Valve FAQs
What output range does the Dungs MB-DLE 412 B01 S20 cover?
About DN25 motorised regulating valve (per the Dungs published gas solenoid valve range); the exact duty is confirmed against your boiler or furnace on request.
Which applications suit the Dungs MB-DLE 412 B01 S20?
The MB-DLE family is the combined shut-off + regulator that replaces a separate valve and regulator in one body.
How is the Dungs MB-DLE 412 B01 S20 controlled and supplied?
It is mb-dle 412 b01 s20 and Zhongli Weiye stocks the Dungs MB-DLE 412 B01 S20 as a compatible spare / stocked supplier, verified against the customer's burner before supply.
Can the Dungs MB-DLE 412 B01 S20 be used for gas trains needing shut-off + modulation?
Yes — the MB-DLE 412 B01 S20 is sized for gas trains needing shut-off + modulation; Shut-off + motorised regulation
What makes the Dungs MB-DLE 412 B01 S20 different from nearby models in the range?
The MB-DLE412 is the smaller combined shut-off and motorised regulator, below the 415 in flow class.
Can the MB-DLE 412 replace the 415 in an existing train?
Only if the duty is within the 412's lower S20 flow class. The 415 is a larger DN40 S50 body; if the burner needs the higher flow, keep the 415 or size up deliberately.
What is the MB-DLE 412's physical size?
The 412 is the compact S20 / DN25 MB-DLE — the smaller body for small-duty gas trains; if your train needs more flow, the 415 is the step-up size.
When should I pick the 412 over the 415?
Pick the 412 when the burner's gas demand is modest — its S20 spring and DN25 body avoid oversizing the train and keep the valve compact on tight burner fronts.
