Overview Details for NOTCHFLO

Fisher™ NotchFlo™ DST Control Valve

Fisher NotchFlo DST control valves are designed for dirty; cavitating services. The trim in this valve utilizes a series of flow restrictions and expansions to eliminate cavitation; while allowing up to 12.7 mm (1/2 in) diameter particulate to pass through without plugging.

  • Designed to prevent cavitation.
  • Has a pressure drop limit of 290 bar (4200 psi).
  • Can pass up to 12.7 mm (1/2 in) diameter particulate.
  • The protected seat design separates the shutoff function from the throttling function to protect the seating surfaces from throttling wear.
  • Hardened metal seats provide tight shutoff to minimize seat erosion.
  • Cage-type trim allows removal and inspection of parts without taking the valve body out of the pipeline.
