The Fisher 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.
Features include
The valve body meets PN 10 through PN 40, CL150, and CL300 ratings. Face-to-face dimensions meet EN 558, API 609, andMSS-SP68 standards. Line
centering clips provide for versatility to mount and align the same wafer style valve body in different piping configurations (ASME and EN ratings).
The Control-Disk rotary valve features an
eccentrically-mounted disk with either soft or metal seal, providing capability for enhanced shut-off. The interchangeable sealing technology allows for the same valve body to accept both soft and metal seals.
The actuator sizing and selection process is improved by simply reading a table for information.
