Plattco Corporation

Since we invented the double flap airlock valve in the 1960s, we’ve made our living not only in critical applications maintaining an airlock under high pressure, high temperatures, or any other demanding environment but by essentially replacing rotary valves in many industries. They require less maintenance and improve plant efficiency. One inherent defect in rotary valves is that there’s a minimum of .0008 clearance in order for the veins to turn inside the housing. A Plattco valve, at final QA inspection, is anywhere from perfectly flat to a maximum of somewhere around .0002 to .0003 clearance. From the moment a rotary valve is plugged in and starts spinning, the leakage continues to increase with each revolution. The rotor and housing continue to wear. By nature of its actuation, rotary airlock valves are prone to jamming, especially by the introduction of foreign objects (such as tooling, PPE, etc).
