DUNGS solenoid valve MB-DLE 420 B01 S20 (3970182)

DUNGS solenoid valve MB-DLE 420 B01 S20 (3970182) Product number：3970182 MB-DLE 420 B01 S20 is a multi-function combination valve designed for gas systems. It belongs to the GasMultiBloc® series and integrates filtration, regulation, safe cutting and pressure monitoring functions. It is suitable for gas control of burners, boilers and other industrial equipment. It is made of a compact combination of filter, proportional regulator, dual solenoid valves (V1 and V2) and pressure monitor, and the structure is compact. Input pressure: up to 360 mbar (36 kPa) Voltage and power: 230V AC (50/60Hz), power 80 VA. Protection level: IP54, can adapt to dust and liquid splashes in industrial environments. Applicable media: natural gas, liquefied gas and other non-corrosive gases (class 1, 2, 3 gases and neutral gaseous media). Core functions one. Safe gas cutoff Double solenoid valve design: V1 is a fast opening/closing valve, V2 is a slow opening/fast closing valve, and it is equipped with the main flow throttler, which can control the gas flow in stages to prevent pressure fluctuations and backlash. Emergency cutoff: When power is cut off or abnormalities are detected (such as gas leakage or overpressure), the valve will automatically close within 1 second and need to be manually reset before it can be opened again, which complies with safety management specifications. two. Precise pressure regulation Built-in proportional regulator can sensitively adjust the output pressure according to combustion requirements, with an accuracy of up to ±15%, suitable for high flow scenarios under low pressure differentials. Hydraulic opening hysteresis technology reduces pressure shock and ensures combustion stability. three.Integrated monitoring and diagnosis Pressure monitor: can be connected to external pressure switches (such as GW 150 A5) to monitor the rear pressure of the valve in real time to prevent overpressure or undervoltage operation. Test connection point: Provides a G1/8 interface for easy detection of gas pressure and valve status. four. Compatibility and Extension The modular design supports external ignition gas taps, valve detection systems (such as VPS 504) and terminal switches, adapting to complex combustion control needs.
