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.

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

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.

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
the pipe wall. The valve can be matched to the bore
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.

Ease of installation–Full flanging on the valve body
allows the valve body to be easily aligned centrally
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.
