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
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.
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 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.

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.
ceramic ball for particularly aggressive slurry services with extended lifetime requirements. The ceramic insert offers substantial increase in flow ring lifetimes.
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
Trim materials are available to meet the requirements of corrosive/erosive slurries. See table 2.
The “Flow Over the Top” V-Notch Ball offers an 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.
