Introduction: Fisher/Fisher NotchFlo™ DST control valves are designed for use in dirty, cavitation applications. The trims in this valve utilize a range of flow restrictions and extensions to eliminate cavitation, allowing particles up to 12.7 mm (1/2 in) in diameter to pass through without clogging.
Features:
Pressure drop limit 290 bar (4200 psi).
Particles up to 12.7 mm (1/2 in) in diameter are allowed to pass through.
The protective seat design separates the cut-off function from the throttling function and protects the seat surface from throttling water.
Hardened metal seat provides tight shut-off capability, minimizing the potential for seat corrosion.
