product details
1, Dfb-20 / 2 mine flameproof solenoid valve is a new product developed for the harsh underground environment of coal mine. It completely overcomes the defects of common pilot solenoid valve, such as small nominal pressure, poor working reliability, easy blockage and leakage. It is suitable for allowing the methane and coal dust in the surrounding air not to exceed the safety regulations of coal mine The safety content specified in is used in the mine as water, emulsion, oil and liquid pipeline with small viscosity, non inflammable and no suspended substance to control full opening and full closing. This product is designed and manufactured in strict accordance with GB3836-2000, MT / t715-1997 and Q / ahj035-2014.
2, Model meaning
DFB – 20 / 2
DFB stands for: basic code of solenoid valve.
20 for diameter of solenoid valve, unit: mm
2 for: maximum working water pressure, MPa
