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 operation.

No special tools are needed to access the strainer basket for cleaning. The chamber is first drained, then the castle nuts loosened, then the cover is lifted and swung clear of the chamber opening.

The diverter system consists of high quality stainless steel balls and teflon seats to ensure exceptionally long seat life and positive sealing.

For basket servicing there is a drain plug for each strainer chamber and a vent valve on top of each strainer chamber.

Should service of diverter components become necessary, it's easy to accomplish. There is no need to remove it from the line.

All kinds of strainer baskets are available for every application. They include perf with 1/32" - 1/2" hole size and 10 to 400 mesh liners.

Type D125TCIC & D125FCIC Cast Iron; D150TDIC & D150FDIC Ductile Iron; D150TCSC & D150FCSC Cast Steel; D150TSSC & D150FSSC Cast 316SS; D150TBZC & D150FBZC Cast Bronze

The duplex strainer has two separate strainer basket chambers. These chambers are put into service independently. When operating basket chamber shows a high pressure drop the flow is switched to the other one. The clogged basket chamber is then cleaned or replaced, ready for use again. Thus the duplex strainer can provide uninterrupted operation.

Sure Flow Tri Ball Duplex Strainers serve to remove dirt and debris from pipelines and protect sensitive system components. The Tri Ball Duplex keeps the out of service chamber empty during operation. Thus you have enough time to clean or replace the strainer basket without ever having to worry about leakage and overlow.

A unique flow diverter ball valve system isolates the two strainer basket chambers. One is operating when the other is idle or its basket is being replaced. An easy-to-turn handle diverts the system flow from one chamber to the other so the flow in the pipeline is never shut off.
