DF400 Eccentric Rotary Plug Valve

Heavy-duty eccentric plug valve with a self-aligning, straight-through path.

The DF400 is a heavy-duty eccentric plug rotary (globe) control valve combined with a low-profile spring-and-diaphragm actuator. A self-aligning eccentric plug with a straight-through flow pattern gives tight shutoff at higher flow capacities in severe service.

Key Features
  • Self-aligning eccentric plug, quarter-turn
  • Flanged body, RF end connection
  • Standard low-emission packing
  • Blowout-proof shafts, reduced-port trim, NACE options
