DHF SERIES
Auto Double-Hammer Counterweight Flap Ash Valve
HSX Auto Double-Hammer Flap Ash Valves utilize dual counterweighted balanced flaps arranged in series. Relying entirely on material gravity and adjustable counterweights, the dual flaps open and seal alternately, delivering non-powered zero-airlock continuous ash discharge from negative pressure baghouses and cyclones.
