This product uses an explosion-proof electromagnet to prevent the explosion of mixed gas in the explosion-proof valve and to avoid the explosion of dangerous gases in the external environment. This type of electromagnet housing can withstand the explosive pressure of the internal explosive gas mixture and prevent internal explosions from propagating around the casing.
|Flameproof electromagnetic reversing valve
||GB4:use in dangerous ground
GB12: used in mines
|Flameproof electro-hydraulic reversing valve
|Flameproof electromagnetic relief valve
01.high flameproof level, safety factor
