The Fisher Vee-Ball Valve Family
Vee-Ball rotary valves combine the features and
performance you need. These features are made
available through expertise in applications, valve
design, and manufacturing.
The valves are suitable for throttling or on-off
service. They are often used with a full 0 to 90
degree ball rotation.
Fisher V150, V200, and V300 Vee-Ball valves use
the time-proven V-notch ball that provides
high-capacity control of liquid, gas, steam, and
fibrous slurries. The shearing action of the ball
allows smooth, non-clogging operation, and the
unrestricted, straight-through flow ensures high
capacity.
Easy Installation . . . Fisher V150 and V300 integral
flanges eliminate exposed flange studs, and the
V200 features line-centering lugs to simplify
alignment.
High Rangeability . . . Flow coefficient ratio is 300
to 1.
Reduced Maintenance Costs . . . The V150, V200,
and V300 valves have interchangeable trim parts to
reduce spare parts inventory and cost and simplify
maintenance procedures and training. Metal and soft
seals are interchangeable within a valve body.
Protection Against Process Fluid Emissions . . .
Optional ENVIRO-SEAL packing systems provide an
excellent shaft seal to prevent the loss of valuable or
hazardous process fluids. These live-loaded
systems provide long packing life and reliability.
Materials for Sour Service . . . Emerson Process
Management offers materials and manufacturing
procedures for compliance with NACE (National
Association of Corrosion Engineers) standard NACE
MR01752002, MR0103, and MR0175 / ISO 15156.

Easy Seal Inspection . . . Seals can be inspected
without removing the actuator or disassembling the
valve.
Noise Attenuator Ball. . . Depending on service
conditions, up to -10dBA acoustical attenuation and
a K
C
of 1.0 for liquid flow are possible with the noise
attenuator ball (available with DN 100 through DN
300 and NPS 4 through 20 valves).
Basis Weight Control Valve . . . Fisher V150,
V200, and V300 valves are available to meet the
precision control requirements of basis weight
control in the paper-making industry.
Other Rotary Products
Fisher V500 Valve . . . The V500 valve uses rugged
valve components and a choice of erosion-resistant
trim materials for highly erosive and severe
operating conditions at pressures to PN 100 (CL600)
and temperatures to 538C.
Fisher CV500 Valve . . . The CV500 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 high capacity,
erosion resistance, and pressure control for liquid
and gas.
