Aerodyne Environmental’s newly designed Vacu-Valve airlock valve offers a square flange or circular flange for more versatility. The trickle valve operates as a constant discharge valve for dust collectors, hoppers, cyclones and other equipment operating under negative pressure. Its duck bill design allows it to dispense free-flowing material continuously. It is available in the open design of the Platypus or the closed design of the Armadillo.
