DIF & DIT IRON DUPLEX STRAINERS

See all Duplex Strainers

OVERVIEW: The DIF (flanged) and DIT (threaded) duplex strainers are the go-to solution for low- to medium-pressure systems requiring continuous operation without shutdown. With rugged cast iron construction and a smart diverter design, they let you clean one stainless steel basket while the other remains in service—keeping flow going, always. Ideal for general water or process applications at up to 200 psig @ 150 °F, these units combine durability, ease of use, and value in one compact design. For 6" or 8" sizes see the DIFL Model. Also with Carbon Steel or Stainless Steel bodies.

FEATURES:

    •  Dual-basket design: switch flow between chambers for uninterrupted operation
    •  Stainless-steel diverter balls with PTFE seats: ensure tight shutoff and reduced leakage
    •  Low-torque switching handle: clearly indicates which side is in service
    •  1/16″ perforated stainless steel baskets: standard 41% open area for balanced flow and filtration
    •  Quick access covers: tool-free maintenance and basket removal
    •  Pressure rating: 200 psig at 150 °F (liquids only)
    •  Proven performance: trusted design used in countless municipal and industrial installations
