The Vacu-Valve: Low Maintenance Trickle Valves from Aerodyne

An operational diagram of the Aerodyne trickle valve Vacu-Valve illustrating its passive vacuum-sealed design, elastomeric sleeve construction, and low-maintenance functionality as a rotary valve alternative.

Aerodyne Vacu-Valve® Platypus and Vacu-Valve® Armadillo

Featuring the Platypus trickle valve and Armadillo trickle valve.

The open-construction Platypus and the closed-construction Armadillo Vacu-Valve trickle valves are the most economical ways to manage dust discharged from bag filters or cyclones under negative pressure. Its fitted duckbill sleeve adjusts to the desired system vacuum, and material is continuously discharged.

Vacu-Valves can be used in higher temperature applications, and are typically available at a fraction of the cost of the rotary airlock valves they replace. Additionally, they require no controls, lubrication or power supply, and easily handle abrasive materials.

The Vacu-Valve operates based on the equilibrium between the vacuum in the system above it, the particulate size, shape, mass and physical characteristics. The sleeve forms an airlock when exposed to negative pressure above it. The vacuum must be less than -16″ W.C. to pass solids. Solids will build up in the Vacu-Valve as the vacuum and sleeve friction resist, letting the particulate out. The force of gravity and weight of built-up particulate force the particles down through the sleeve until they fall out of the bottom. Fine particles with a spherical shape (ex. sand) work best. Flow rates vary based on the particulate characteristics and operating conditions. Contact an Aerodyne representative to see if this valve will work for your application. Available in 8″ and 10″ flange size.
