Fisherr CV500 Rotary Control Valve
The Fisher CV500 Cam Vee-Ballt control valve
combines the rangeability of the cammed-segmented
V-notched ball, with the inherent ruggedness found in
the V500 heavy duty bearings, seals and body. This
combination provides a balance of erosion resistance
and pressure control for gas and liquids. The
unrestricted, straight-through flow design provides
high capacity for gas, steam, liquids, or fibrous slurries.
The flanged and flangeless valves feature streamlined
flow passages, rugged metal trim components, and a
self-centering seat ring (figures 1 and 2).
With these components, the CV500 valve, designed
for throttling or on-off applications, combines globe
valve ruggedness with the efficiency of a rotary valve.
Matched with a Fisher power or manual actuator, the
CV500 valve dependably controls fluids in many
process industries.

FLANGED VALVE WITH FISHER 1052 ACTUATOR AND
FIELDVUE™ DVC6200 DIGITAL VALVE CONTROLLER

Features

Excellent Flow Characteristic–Precise contouring of
V-notch ball provides a modified equal percentage
flow characteristic.

High Capacity–Unrestricted, straight-through, flow
design provides greater capacity than many
conventional globe and rotary eccentric plug valves.

Long Seat Life–The V-notch ball cams into and out
of the seat minimizing contact with the seat ring for
reduced wear and friction (figure 3). V-notch ball
doesn't contact seat during throttling operation.
S31600 (316 stainless steel) or R30006 (Alloy 6)
seat ring has two shutoff surfaces and can be easily
reversed, reducing downtime.
