Design V150S Slurry Vee-Ball Control Valve
 |
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.
- 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. - Longer 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 longer 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.
