DFB-20/6 Mining explosion-proof solenoid valveDetailed product description：

DFB-20/6 mining explosion-proof solenoid valve is mainly suitable for dust reduction and removal in hazardous environments containing coal dust and explosive gases underground in coal mines; This solenoid valve is designed and manufactured based on the principle of AC electromagnet, in accordance with the relevant regulations of "G B3836.1-2010, GB3836.2-2010, MT/T715-1997, Q/SHT36-2020". It can also be used in industrial sectors such as power generation, chemical industry, metallurgy, and light industry as an automatic control for liquid, gas, and other pipelines. It is the basic component for achieving pipeline automation.

Main parameters of DFB-20/6 mining explosion-proof solenoid valve
Working voltage: AC127V;  
Maximum working pressure: 6MPa;  
Nominal meridian: 20mm
Opening method: normally closed type, which opens when powered on and closes when not powered on;

Functional Features
The electromagnetic part of the solenoid valve adopts an explosion-proof structure, which places the electromagnetic coil and other components inside a metal explosion-proof shell. When sparks occur inside the shell, it will not ignite the external coal dust and explosive gas mixture.  
The solenoid valve is normally closed and in a closed state without power. When powered on, the solenoid valve opens. When the power is cut off, the valve closes.
