Straight-through electromagnetic pulse valve straight-through electromagnetic pulse valve referred to as pass-through valve, its import and export is 180 degrees, straight-through electromagnetic pulse valve which import and export center for the same line, it is suitable for installation and connection accumulator with dust blowing tube, stream flow, to meet the requirements of the pulse cleaning air stream. Passing Electromagnetic pulse valve is composed of solenoid pilot valve and the main valve in two parts, when energized, the core is drawn from the electromagnetic force, the pilot valve port opening, the film medium pressure plate on the chamber drops and the valve inlet side pressure drop, due to the increase compared to the inlet end of the pressure valve, diaphragm pushed the media into the outlet end of the valve was turned on. When the power failure, the core gravitationally and spring return, close the pilot valve port, so the diaphragm chamber pressure rises, the diaphragm is pushed down to close the main valve mouth, then the valve was closed.
