DUNGS solenoid valve MB-DLE 405 B01 S20 (3970530)

DUNGS solenoid valve MB-DLE 405 B01 S20 (3970530) MB-DLE 405 B01 S20 (3970530)‌ is a multi-function gas combination valve in the German DUNGS series. It is specially designed for burner systems, integrating adjustment, control and safety functions. Brand: DUNGS Model: ‌MB-DLE 405 B01 S20‌ (3970530), belonging to the MB-D(LE) series multi-function combination valve‌. Structure and Design: Compact design, integrated filters, regulators, valves and pressure monitors to reduce installation space. The interface is Rp1/2 pipe thread (ISO 7/1 standard), which is easy to connect to the pipe. ‌Applicable media and environment‌: Suitable for ‌1, 2 and 3 gases and neutral gas media, containing H₂S≤0.1% dry gas‌. Working ambient temperature: -15℃ to +70℃. ‌Core Functions‌ ‌one.Dual valve control‌ Contains two valves: ‌V1‌: Quickly open the valve for main gas on and off. ‌V2‌: Slowly open the valve, with main flow adjustment function, supporting precise control of gas flow‌. Comply with the ‌DIN EN 161 Class A Class 2 safety standard, with a shutdown time of <1 second to ensure quick response‌. ‌two.Pressure regulation and monitoring‌ Integrated ‌proportional regulator‌ (DIN EN 88 standard) for sensitive adjustment of output pressure (4–20 mbar). Maximum operating overvoltage: 360 mbar, suitable for high flow demands with low pressure difference‌. ‌three.Safety features‌ Equipped with a fine filter to prevent dirt from entering the air duct. It is recommended to install a gas filter at the front end. Supports pressure monitor installation (such as GW...A2 series) for burner pressure detection‌. Working voltage: AC 220-240V (50-60Hz), DC 24V can be selected. Protection level: IP54, suitable for industrial environment‌. ‌Application Scenarios‌: It is mainly used in gas burner systems, such as industrial boilers, heat treatment equipment, etc. Suitable for gas supply scenarios that require high safety and precise flow control.
