Plattco Corporation specializes in valve engineering for conveying, processing and isolation in a wide variety of industrial applications.

We incorporate more than fifty years of valve expertise and over seventy-five years of metallurgical and manufacturing experience into each product line.

We design and manufacture only the highest quality flap valves, knife gates, and isolation slide gates that are used for feed and discharge of product or waste in over 100 industries worldwide. Plattco is the standard by which valve performance is measured.

History
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 1930’s.

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 1960 to eliminate leakage with sintering and palletizing in the mining industry, and for 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.

Plattco is an integrated manufacturer, with our own engineering, pattern shop, foundry and machine shop in Plattsburgh, New York. The company owns several U.S. and International patents and is the premier innovator in the solid materials handling valve business.
