Duplex Cartridge Strainer

SS Filters duplex strainers and duplex filters provide a simple, cost effective way to separate particle impurities from fluid systems. Duplex strainers are ideal for applications where continuous flow must be maintained with no flow interruption for cleaning. These filters are available with basket type strainers as well as cartridge strainers having desirable micron ratings.These duplex strainers have a butterfly valve that directs flow through either side without shutting off the flow. A valve handle guard shields the side in use. The standard valve handles swings over. the inlet port. Special reverse valve handles that swing over the outlet port can also be furnished. An adjustable locking flange holds the valve plug on its seat.

These duplex strainers and duplex filters protect pumps, engines, nozzles, valves, heat exchangers and other expensive pipeline equipment from harmful flow contamination by catching dirt and debris.

Basket strainers feature top removal of the filter screen. The screen is in the form of a basket with a lifting handle, so that all particulate captured and retained by the screen can be easily removed for disposal. They are intended for applications where large amounts of solids particulate are expected and where the clean a out will be frequent.
Where fine filtration is required, the basket is replaced by cartridge filters. During cartridge cleaning or change out, the housing can be cleaned by opening the lower plug.
