Fisherr V150S
Slurry Vee-Ball™ Control Valve

The Fisher V150S Slurry Vee-Ball valve mates with
CL150 raised face flanges. Rugged construction, highly
wear-resistant trim materials, and an unrestricted
straight through flow path make the design ideal for
controlling the most abrasive of slurries.

A shaft with a choice of drive connections will allow a
variety of power operated actuators and valve
positioners or controllers to be used.

W8512

The design is particularly effective in minimizing
erosive damage to the adjoining pipework, thereby
providing greater operational safety and service life
when compared with other valve types.

Features

 Fully protective trim–The valve body, shaft, and

bearings are fully protected by hard wear-resistant
trim materials.

 Pipeline and flange protection–The throttled flow

stream is guided through a specially shaped flow
ring to minimize turbulence and impingement on
thepipewall.Thevalvecanbematchedtothebore
size of the inlet and outlet piping in order to prevent
turbulence being generated by the step resulting in
scouring erosion of the flange faces, unexpected
leakage, and expensive rework. In addition, both
the inlet and outlet valve flange faces are protected
by a portion of the hard trim.

Fisher V150S Slurry Vee-Ball Control Valve

 Long Service Life–The Vee-Ball design, when used in

reverse flow mode, keeps the high velocity down
stream of the vena contracta within the flow ring
bore at the outlet of the valve. Compared with other
styles of valves, the exit flow is essentially parallel
with the flow ring wall and a minimum of flow
impingement occurs. Combined with a choice of
hard wear-resistant materials, a significantly long
life is obtained.

Easily replaceable trim parts allow the valve to be
overhauled at predetermined intervals and the
valve body used again during repeated operational
cycles.

 Ease of installation–Full flanging on the valve body

allows the valve body to be easily aligned c entrally
with the pipe flanges, an essential requirement in
avoiding erosion across the flange faces.

 Excellent Flow Control–Precise contouring of the

V-notch ball provides a modified equal percentage
flow characteristic. When combined with a valve
actuator/controller system having minimal lost
motion, improved process control can be obtained.

Features (continued)

 Quick and Easy Maintenance–All trim parts are

retained without the use of press fits or screw
threads exposed to the process fluid. See figure 1.

 Structural Integrity–The valve body, complete with

flanges, is made from a one-piece casting. No
welding is employed. No O-ring seals are used. Use
of a flanged valve body does not require the use of
extra long studs.

The shaft seal is made from well-proven PTFE
chevron ring packing with the means for external
adjustment.

Options

 A PSZ (partially stabilized zirconia) ceramic flow ring

insert is available with HCI (high chrome iron) or PSZ

ceramic ball for particularly aggressive slurry
services with extended lifetime requirements. The
ceramic insert offers substantial increase in flow
ring lifetimes.

 Trim materials are available to meet the

requirements of corrosive/erosive slurries.
See table 2.

 The“FlowOvertheTop”V-NotchBalloffersan

alternative to the standard V-Notch Ball in scaling
applications.

 The drive shaft is available with either a double D or

splined actuator connection to accommodate a
choice of actuation between a spring-opposed
diaphragm or a rack and pinion.
