Specialized dust collection systems are provided that include a pulsed air system; at least one diaphragm valve assembly, which functions as the pulsed air valve; and a controller for controlling the diaphragm valve assembly and pulsed distribution of the pressurized air. The diaphragm valve assembly may be controlled by the controller and is operable to selectively deliver pressurized air to the air distribution assembly in short pulses or bursts. The disclosed diaphragm valve assembly can be utilized to improve the functionality of the pulsed air system and the dust collection system.
