Emerson Process Management expands its Fisher control valve series to include the NotchFlo DST valve and Fisher DST Trim

Emerson Process Management has expanded its line of Fisher dirty service control valve solutions to include the NotchFlo DST valve and Fisher DST Trim. With the expanded line, Emerson is able to provide specific solutions that both increase process availability and reduce maintenance costs for a range of severe service applications. The lineup offers improved cavitation control for applications known to contain entrained particulate that would damage standard trim components.

The Fisher NotchFlo DST valve is a multi-stage (three-, four- or six-stage) anti-cavitation valve available in Class 300 – 1500 Globe and Class 600 – 2500 Angle (NPS of 1-8) that can be used in severe service applications.

The Fisher DST Trim is a multi-stage (two-, three-, four-, five- or six-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).
