Specialized Valve Trim Controls Flow and Pressure Drop



Fluid process control operations can entail fluid velocities, pressures, or other characteristics that can prove challenging on a number of levels, not the least of which is flow control. Valve manufacturers have developed a wide array of specialized designs and configurations to provide flow control while mitigating or eliminating some undesirable effects associated with restricting fluid flow.

Inherent in the restriction of flow is the possibility of creating or increasing some generally undesirable conditions in the pipe.
  • Velocity
  • Noise
  • Vibration
  • Erosion
  • Cavitation
Depending upon the process conditions, any of these elements could have a decidedly negative impact upon process performance, workplace environment, or system longevity. The video provides an example of how one manufacturer of severe service ball valves, Mogas, modifies their design to address these potentially negative aspects while providing accurate flow control. By adding elements to the outlet side of a ball valve, an entirely different operating profile is achieved. Watch the video for all the details, as it is well produced and illustrated.
