Trickle valves provide a low-cost, efficient, and durable means of controlling a dust collector’s discharge. A hinged plate maintains the seal between the collector and the discharge. Once the accumulation of dust exceeds the vacuum pressure, the plate of the trickle valve releases and allows the material to flow via gravity.
Trickle valves are available in multiple sizes, use only one moving part, have no electrical connections, are easy to inspect, and can withstand abrasive materials and heavy minerals (100 lbs/pi³ and more).
