Plattco valves allow for safer and easier inline repair and maintenance while eliminating problems with:
We invented the Double Flap Airlock Valve in the 1960's and since that time a very significant portion of our business each years comes from replacing rotary valves in many industries world-wide. Not only can our valves perform in critical applications maintaining an airlock under high pressures/ temperatures in demanding applications, but we also have valves designed specifically for pollution control and nuisance dust.
While rotary valves have their place in the market, Double Flap Airlock Valves are purchased in many applications in place of rotary valves by leaders who insist on a solution that offers less maintenance and improves plant efficiency. A Plattco Double Flap Airlock Valve seals tighter than a rotary valve as there are no clearances required in the design.
While the clearances in rotary valves increase at elevated temperatures (causing more leakage), a Plattco Valve remains constant. Plattco provides a long-term solution to rotary airlock wear by eliminating the rotary action of the valves.
