The Eaton Model 570 Duplex Basket Strainer has been specifically designed to remove potential damage causing particles from large volumes of water and other process media efficiently and cost effectively. It operates continuously and the pipeline flow never has to be shut down for strainer basket cleaning. Flow is switched from one basket chamber to the other by a sliding gate mechanism operated by hand wheels. The free floating valve disc mechanism moves easily and does not bind. The valve operating stem is fully enclosed, protecting it from the fluid flow.
