Fisher DST Trim anti-cavitation valve trim

The Fisher DST Trim is a multi-stage (2-, 3-, 4-, 5- or 6-stage) anti-cavitation trim available in Class 300-2500 (NPS of 1-16). Both the NotchFlo and DST are frequently used in high-pressure drop applications up to 4200 psi (290 bar) in the chemical, refining, oil and gas production, and power industries.

The DST Trim is part of an expanded line of dirty service control valve solutions designed to help increase process availability and reduce maintenance costs for a broad range of severe service applications. The range offers cavitation control for applications known to contain entrained particulate that would damage standard trim components and can be used in the hydrocarbon, power, chemical, pulp and paper, and metals and mining industries
