Fisher™ Control-Disk Valves
Fisher Control-Disk valves provide precise control across a broad range of applications.
Fisher™ Control-Disk™ Valves

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.

A Control-Disk valve 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.

CASE STUDIES
Innovation In Design

With a contoured edge on one side, the unique and patented disk creates a flow clearance to give the Control-Disk valve an inherent equal percentage characteristic. Computational fluid dynamics (CFD), verified by flow testing, show the Control-Disk valve’s ability to reduce dynamic torque.

Wide Control Range 

Process gain defines the relationship between changes in process output and input. The travel over which process gain stays between 0.5 to 2.0 is a valve’s control range. When process gain is not within 0.5 to 2.0, poor dynamic performance and loop instability can occur. Control-Disk valves have a wide control range of 15–70% and excellent throttling control.
