'''Vacuum Valves''', also known as [[Trickle Valves]], are commonly used in industrial dust collection applications to maintain an [[Airlocks]] seal on a dust collector [[Hoppers|hopper]] while allowing bulk solid material to be automatically discharged. These [[Valves]] are typically a less expensive alternative to more commonly used [[Rotary Airlocks]]. Unlike rotary airlock valves which are driven by either [[Electrical Actuators]] or [[Pneumatic Actuators]], trickle valves require no external power source. | '''Vacuum Valves''', also known as [[Trickle Valves]], are commonly used in industrial dust collection applications to maintain an [[Airlocks]] seal on a dust collector [[Hoppers|hopper]] while allowing bulk solid material to be automatically discharged.
