Original valves were installed in mid 1970s, with some originals still installed and running 53 years later! Plattco Double Flap Airlock® Valves are an industry standard around the world and are preferred by engineers and end users for this application because the seal is critical. Without the superior Plattco seal, the ore fines are sucked through to the ID fan, and then the ID fan wears out quickly. ID fans can cost as much as $250,000.
