Plattco began as a gray iron foundry in 1897 – producing drainage castings, stock valves, and other machined castings for the paper, mining, and other regional industries. Always a leader, Plattco became the first licensee for “white irons” (Ni-Hard, Hi-Chrome, Ni-Resist) patented by International Nickel in the 1930s.
Our customers have always looked to us for solutions to their most difficult dry material handling issues. This problem-solving role led us to invent the first Double Flap Airlock® Valves in the 1960s to eliminate leakage with sintering and palletizing in the mining industry, and handling of cement clinker.
Since then, we have engineered thousands of solutions in dozens of industries throughout the world. We have established an unmatched reputation for correcting process design problems in applications that involve high temperature, high pressure, and abrasive or corrosive materials.
Every day Plattco brings value to our customers by offering integrated solutions and programs that are fully-customizable to meet exact specifications.
Plattco Corporation continues to specialize in industrial valve engineering for conveying, processing, and isolating in a wide variety of industrial applications. We incorporate decades of industrial expertise and over a century of metallurgical and manufacturing experience into each product line.
We design and manufacture only the highest quality Double Flap Airlock® Valves and slidegates that are used in over 100 industries worldwide.
Plattco is the standard by which valve performance is measured. We hold several US and international patents and are the premier innovator of airlock valves and slidegates used in dry material handling applications throughout the world.
Plattco is an integrated manufacturer with our own in-house engineering, quality, and safety teams, and on-site foundry and machine shop, spread across our founding campus in Plattsburgh, New York.
