Emerson Expands Dirty Service Control Valve Solutions

Expanded Fisher® line offers cavitation control for a broad range of severe service applications

MARSHALLTOWN, IOWA (February 8, 2010) - Emerson Process Management has expanded the line of Fisher® dirty service control valve solutions to include the NotchFlo(TM) 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 broad range of severe service applications. The line-up offers excellent 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.

The Fisher NotchFlo DST valve is a multi-stage (3, 4, or 6 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 (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.

In addition to the expanded line-up of Fisher dirty service control valves, the Fisher Cavitrol(TM) III Trim with Improved Sealing Technologies is available. It is a multi-stage (2 or 3 stage) trim available in Class 900 - 2500 (NPS of 1 - 8x6) that can be used in severe service applications where plug tip erosion and seal wear are issues. The Fisher Cavitrol III Trim is frequently used in pump recirculation and startup systems in the power, process, oil production, chemical refining, and other industries.
