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
forthrottlingoron-off applications, combines globe
valveruggednesswiththeefficiencyofarotaryvalve.
Matched with a Fisher power or manual actuator, the
CV500 valve dependably controls fluids in many
process industries.

Product Bulletin

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.

 Simple Assembly and Maintenance–No special

orientation, precision clamping or repetitive
centering of V-notch ball and seat ring is required
when tightening the retainer, promoting accurate
alignment and easy assembly.

Features (continued)

 One-Piece Body–Valve body is cast in one piece.

There are no body gaskets to leak as a result of
pipeline stresses.

 Operational Versatility–Self-centering seat ring and

rugged V-notch ball allow forward or reverse flow
with tight shutoff in either flow direction.

 Easy Installation–Integral valve flanges mate with

many different classes of pipeline flanges, satisfying
a variety of piping requirements. Flanges eliminate
exposedlineflangebolting, shorten alignment and
installation time, and promote secure valve
installations and piping integrity. Flangeless valves
are automatically self-centering on line bolting for
easy installation.

 Sour Service Capability–Trim and bolting materials

are available for applications handling sour fluids
and gases. These constructions comply with the
requirements of NACE MR0175-2002.

 Rugged Construction–Durable, solid metal seat

ring and ball shut off tightly. Oversized shaft
diameters and rugged trim parts allow high
pressure drops.

 Reliable Performance–The seat ring design (figure

1) self-centers, self-laps, and dynamically aligns with
V-notch ball, giving superior cycle life. Optional
sealed metal bearings help prevent particle buildup
and valve shaft seizure in severe applications.
