The Eaton Butterfly Valve Type Model 52 Duplex Basket Strainer is a special design with several important features and advantages for large size pipeline with high flow rates. Flow is switched from one basket chamber to the other by a pair of synchronized, high quality butterfly valves. This replaces the diverter plug used on smaller size strainers and gives a straight flow pattern with no sudden changes in flow direction. The result is a very low pressure loss. A 10″ strainer of this type, for example, can handle a water flow rate of 2,000 gpm with a pressure drop of only 2 psi. This is the strainer to choose when you have a high flow rate application and a low pressure loss is critical.

For larger size pipelines with high flow rates the Eaton Model 50 Butterfly Valve Duplex Strainer offers several unique features and advantages over other large size strainers. Among them are low pressure loss, operator friendly quick opening covers that do not require lifting gear, a compact design with a smaller footprint than other strainers, and a special basket design to maximize time between basket cleanings.
