Available in sizes from 1 to 4 inches bore, flanged to ANSI 250 FF and 300RF, units can be drilled to BS and DIN standards.
This basket filter can be used for continuous service without interruption to the flow even during cleaning of the basket.
Within a single Duplex filter there are two basket chambers each rated to handle 100% of the liquid flow, plus an integral valve mechanism that enables the flow to be diverted through either chamber.
The integral valve mechanism is safer than an operating / standby piping layout incorporating separate valves, because the flow there can easily be interrupted if the valves are operated in the wrong sequence.
Standard features of the Plenty Duplex Strainer include a single lever action on the changeover valve, which eliminates the possibility of hydraulic shock and accidental interruption of the flow, and fixed stops to indicate which chamber is in use.
It also incorporates a projecting flange from the valve lever which guards the chamber cover being used in order to avoid the wrong cover being inadvertently opened.
The issue of easy maintenance has also been taken into account, with the inclusion of quick release covers, eliminating the need for tools.
Further, top mounted covers remove the need for draining basket type chambers, associated with element removal.
