Valves
When capacity and performance are the requirements rotary valves are the answer. Popular rotary products include butterfly, eccentric plug, full bore pipeline, high performance butterfly and segmented ball
The eccentric plug rotary control valve features an eccentrically mounted plug or ball, which combines rotary valve efficiency with globe valve ruggedness. The Fisher® V500 is designed for severe and/or erosive service and features sealed bearings, an oversized one piece valve shaft and a variety of replaceable wear resistant trims ranging from SST to Ceramic. The Fisher CV500 features the same ruggedness of the V500 but uses a segmented ball as the control member rather than a plug. The CV500 has higher capacity than the V500 and features an equal percentage characteristic for better control performance. Both of the valves feature a splined valve shaft, which provides zero lost motion when coupled to a Fisher rotary actuator.
