Sureflow Duplex Strainer, Cast; Steel, Stainless Steel, Iron or Bronze, 5,6,8 Inch, ANSI Flanged

Removes dirt & debris from pipelines, with the duplex feature a design that makes strainer basket servicing a no-hassle, no-downtime operation.

A unique diverter valve cartridge design isolates the two strainer basket chambers from one another. Before operating the handle a manual, integral lifting jack, built into the strainer is used to lift the diverter plug off of its seat. After the switching operation, the lifting jack is used to reseat the plug. The lifting jack is specially designed to lift and seat the plug easily, even under high pressures. A built-in stop limits the distance the diverter plug can be raised. This minimizes the possibility of material bypassing the plug while it is rotated. It also prevents debris from building up under the plug and making it difficult to reseat. An easy to turn handle operates the cartridge and diverts flow from one chamber to the other, the flow is never shut off, and the position of the handle clearly indicates at all times which chamber is in service. No special tools are needed to access the strainer basket for cleaning. The dynamic diverter cartridge seals prevent fluid bypass into the out of service chamber, the chamber is first drained through the NPT drain tap and then the swing away yoke-design cover is swung clear of the chamber opening, the basket is removed by its lifting handle.

All sizes are provided with mounting legs to bolt the strainer to the floor for a rock solid installation.
