Emerson Announces Extended Line Sizes for the Popular Fisher® Control-Disk(TM) Valve

Fisher Control-Disk valve now available in sizes NPS 14 through 24 and ASME Class 150 & 300

MARSHALLTOWN, IOWA - Emerson Process Management announces extended line sizes for the Fisher® Control-Disk(TM) valve. The Control-Disk valve offers excellent throttling performance and is ideal for applications that involve fast processes and varying pressure drops, such as in hydrocarbon, refining, chemical, pulp and paper, and metals and mining industries.

The Control-Disk valve's wide control range is twice that of traditional butterfly valves for better adherence to set point. This improved capability allows control closer to the target set point, regardless of process disturbances, which results in a reduction in process variability.

The Control-Disk valve is reliable and has low maintenance requirements, especially when it is paired with a Fisher actuator and FIELDVUETM digital valve controller, resulting in high plant availability. This assembly can capture and deliver diagnostic data to ValveLinkTM software, providing an accurate picture of valve, actuator, and digital valve controller performance. This makes it a core component of PlantWebTM digital plant architecture.

Selecting the Fisher Control-Disk valve couldn't be easier. As a direct replacement valve, existing piping can be used. Both soft and metal seals are available to address specific application needs.

The new Control-Disk Valve sizes are designed for installation between ASME Class 150 or Class 300 raised-face flanges with flangeless (wafer) or single flange (lugged) body designs. Face-to-face dimensions are in compliance with API 609 and MSS SP-68 standards.
