The VEP/VEM400 series submerged electromagnetic pulse valve is used for the pressure cleaning system of pulse cleaning bag dust collector. When the controller starts the electromagnetic pulse valve, the compressed air in the air bag passes through the pulse valve to the inside of the filter bag to clean the dust adhered to the outside of the filter bag, so as to clean the filter bag, reduce the resistance of the dust collector, and prolong the service life of the filter material.
