Duplex Strainers - Overview

No-Hassle Strainer Basket Servicing
Duplex strainers remove dirt and debris from pipelines and protect sensitive system components. The Model DC Duplex Strainer features a design that makes strainer basket servicing very easy by eliminating seepage during basket cleaning. The Model DC duplex strainer keeps the chamber dry during service. This gives you time to clean or replace the strainer basket without ever having to worry about leakage and overflow. This also results in elimination of clean up after servicing the strainer basket. The Model DC duplex strainer is a modern, technologically advanced duplex strainer.

A Better Duplex Strainer Design
The flow diverter valve cartridge (FDVC) in the Model DC isolates the two strainer basket chambers and prevents fluid bypass. An easily turned handle operates the cartridge and diverts the system flow from one chamber to the other—the flow in the pipeline is never shut off.

When a strainer basket needs to be cleaned, the lever handle is turned to take it out of service and to divert the flow through the other chamber. 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 chamber is first drained and then the cover is lifted and swung clear of the chamber opening. The dynamic diverter cartridge seals prevent fluid bypass into the out-of-service chamber—making for easy, hassle-free strainer basket servicing.

The precision FDVC never requires manual internal or external ball support adjustments—and the low operating torque means the strainer can be operated with an easily turned lever handle.

A double sealing system on both the upper and lower stems guards against leakage. Special reinforced polymer seats are used for extended service life. Should cartridge service become necessary, it’s easy to accomplish by removing four bolts.  The cartridge comes right out through the top of the strainer. There’s no need to take the strainer completely apart or to remove it from the line.

Better for All Applications
The compact, low profile Model DC fits into spaces other duplex strainers cannot yet it still uses full-size strainer baskets and has a low pressure drop performance.
