Fisher™ Control-Disk™ Rotary Valve
Fisher Control-Disk
The Control-Disk rotary valve offers excellent throttling performance.
An equal percentage flow characteristic provides an improved throttling range comparable to that of a segmented ball valve. This improved capability allows you to control closer to the target set point, regardless of process disturbances, which results in a reduction in process variability.
