A pulse valve is a type of valve commonly used in dust collection systems, particularly in baghouse filters. It delivers short, high-pressure bursts of air to clean dust and particles from filter bags or cartridges. The rapid release of air shakes the filter, dislodging accumulated dust and allowing it to fall into a collection hopper. This process is typically controlled by a timer or a controller that triggers the pulse valve at regular intervals, maintaining the efficiency of the dust collection system.
