Eccentric Plug Valves
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.
Fisher® CV500 is a flanged or flangeless eccentric plug valve with reversible metal seat ring and splined shaft. The CV500 is available in NPS 3 through 12, CL150/300/600.
