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.
