Fisher Control-Disk Rotary Valve

Fisher Control Disk Rotary ValveThe 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. 

The control disk rotary valve features an eccentrically-mounted disk with either a soft or metal seal, providing capability for enhanced shutoff. The interchangeable sealing technology allows for the same valve body to accept both soft and metal seals.
