DUNGS solenoid valve MB-DLE 407 B01 S20（3970531）

DUNGS solenoid valve MB-DLE 407 B01 S20（3970531） Product code: 3970531 MB-DLE 407 B01 S20 (3970531) is a multi-function combination regulating valve specially designed for gas combustion systems. It integrates filtration, pressure regulation, valve control and pressure monitoring functions, and is suitable for safety control of industrial combustion equipment. Modular design‌ It adopts a compact structure, integrates filter, regulator, double solenoid valve (V1 fast opening valve + V2 slow opening valve) and pressure switch. The valve body is made of brass alloy, the seal is NBR rubber, and has strong corrosion resistance. Suitable gases: natural gas, liquefied petroleum gas, etc. (Category 1/2/3 gas) ‌Working pressure‌: Maximum 360mbar, output pressure range 4-20mbar‌. ‌Driving voltage‌: DC9V~12V pulse signal (S20 model)‌ ‌Interface size‌: Rp3/4 (DN20) pipe threaded connection‌. Environmental adaptability: Operating temperature -15℃~+70℃, suitable for industrial environments. Core functions‌: ‌one.Safety Control‌ ‌Dual valve coordination‌: V1 is quickly cut off (<1 second), V2 is slowly opened (20 seconds), preventing gas shock‌. ‌Emergency shutdown‌: Supports linkage with the leakage alarm system, and automatically cuts off gas in case of a failure. t‌wo.Flow adjustment‌ Built-in proportional regulator for high flow output under low dropout. The main flow throttle valve (V2) can be manually adjusted to optimize combustion efficiency. ‌three. Pressure monitoring‌ Integrated pressure switch to monitor gas pressure in real time, trigger protection when overpressure or underpressure‌.
