Fisher Control-Disk valve range extended line sizes

Emerson Process Management has announced extended line sizes for the Fisher Control-Disk valve range. The Control-Disk valve is suitable for applications that involve fast processes and varying pressure drops, such as in hydrocarbon, refining, chemical, pulp and paper, and the metals and mining industries.

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

The Control-Disk valve is claimed to be reliable and has low maintenance requirements, especially when it is paired with a Fisher actuator and Fieldvue digital valve controller. This assembly can capture and deliver diagnostic data to Emerson ValveLink software, providing an accurate picture of valve, actuator and digital valve controller performance.

As a direct replacement valve, existing piping can be used. Both soft and metal seals are available to address specific application needs.

The 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.
