| OVERVIEW: The DSF (flanged) and DST (threaded) duplex strainers are engineered for corrosive, sanitary, or high-purity systems where |
| material compatibility is critical. Constructed from ASTM A351 CF8M stainless steel, they stand up to aggressive media, washdown environments, |
| or food and pharmaceutical systems. Just like other Stayflow duplex strainers, they allow cleaning one basket while the other is active—keeping your |
|
system online and clean. Rated for 200 psig @ 150 °F, components rated higher (up to 450 °F in some cases). For 6" or 8" sizes see the DSFL Model. Also with Iron or Carbon Steel bodies. |
FEATURES:
| • No interruption during maintenance: continuous filtration |
| • Perfect for chemical, food, and high-purity applications |
| • 316 stainless steel body and trim (CF8M): superior corrosion resistance |
| • Quick and safe servicing: no tools needed for basket access |
| • Diverter with PTFE seat & stainless balls: ensures clean switchovers and tight shutoff |
| • 1/16″ perforated stainless steel baskets: 41% open area standard |
| • Drain taps & tool-free covers: streamline cleaning |
