Eaton Filtration  offers the all-plastic duplex basket strainer in sizes ranging from 1/2" to 4" made from PVC, Corzan® CPVC or EASTAR® in socket, threaded or flanged options.  

Key advantages of the plastic duplex basket strainer include system component protection, easy basket cleaning, choice of piping connections and wide choice of strainer baskets.  

Protects System Components

The all-plastic duplex basket strainer is ideal when pipeline system components require protection from dirt and debris and the line can be shut down for basket cleaning.  

Unwanted particles are removed as the process media passes through a perforated strainer basket contained inside the strainer body.  

The basket traps the unwanted material while allowing the process media to flow freely. The flow never needs to be shut down for basket cleaning or changing.  

Easy Basket Cleaning

Changing or cleaning the strainer basket is quick and easy in these strainer models.  

Turning the operating handle on the diverter valve assembly switches the flow from one strainer housing to the other.  

Then, the out of service housing can be serviced by opening the hand removable, spin-off cover that features two angled handles for easy access to the strainer basket.  

The housings have external cover threads that do not contact the process media and never need cleaning.  

Venting and draining are made possible by two hand removable, threaded plugs on the cover and side of the housings.  

Choice of Piping Connections

Eaton duplex basket strainers can be installed either in-line or with loop piping configurations.  

This is made possible by changing the orientation of the bottom outlet connection. The connection assembly nuts on the bottom diverter valve need to be loosened and rotated 180 degrees to convert from one type of connection to the other.  

True union connections make it possible to remove the strainer from the piping system without disassembling the piping connections.  

Wide Range of Strainer Baskets

Plastic baskets in perforation sizes from 1/32" to 3/16" are available while stainless steel perforated baskets are available from 1/2" to 1/32" and mesh stainless steel baskets for very fine straining applications are available in sizes from 20 mesh down to 325 mesh.
