Aerodyne’s VHT High-Temp replaceable duck-bill sleeve for the Vacu-Valve is heat resistant in temperatures up to 400°F/200°C and offers resistance to aggressive fuels and chemicals. The Vacu-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 dry, free-flowing material continuously and has no moving parts to maintain. The low-maintenance valve requires no lubrication or power source and has no controls. The valve is suited to “keep-empty” dust-collection units and is available in either carbon steel or stainless steel versions. The replaceable duck-bill sleeves are also available in neoprene or white nitrile, making the unit suitable for general use, high-temperature or abrasive material applications.
