Plattco awarded patent for industrial valve seal
Plattco Corporation, producer of advanced material handling valves for industrial applications, has been awarded a patent for a unique high-pressure mechanical shaft seal that improves the performance and maintenance-free operation of industrial valves in high-velocity, high-pressure conveying systems.
The Plattco High Pressure Mechanical Shaft Seal features a unique design that enables industrial valves to operate flawlessly over long periods in conveying systems that maintain air pressure of up to 42PSI. The Plattco High Pressure Mechanical Shaft Seal is made using corrosion-resistant 304 stainless steel and can operate without the use of an external air source and without adjustment over long periods.
“In designing the Plattco High Pressure Mechanical Shaft Seal, we’ve solved a number of problems experienced by industrial companies that need to convey highly abrasive materials in demanding environments”, said Dean Surprenant, the Plattco engineering manager who played a key role in the product design. “Our new patented design eliminates the excessive wear on valve shafts and housings typically caused by highly abrasive materials under high pressure.”
Plattco was awarded US Patent No. 8128095 for an innovative design that incorporates the shaft bearing into the industrial valve housing as a self-contained cartridge. Plattco also incorporated unique design features that eliminate the need for scheduled lubrication and maintenance, and make the shaft seal easy to replace.
