The FGD unit included as part of its original design several Vee-ball valves that are mainly installed in recirculation lines that are cavitating.
After providing this solution on the first Vee-ball valve vibration was eliminated (as was cavitation) on the valve during normal flow.

It is estimated the customer will now get close to five years out of these valves rather than one.


Due to potential erosion (from the slurry) an attenuator was not an optimal solution and due to capacity issues, erosion, and costs a globe style valve was not a viable alternative.
It was decided (after a year of selling this solution) to aspirate air into the valves to cushion the bubble collapse. Also, the local engineer looked at re-piping the recirculation line (to allow the cavitation to “blow” into the vessel) but determined engineering and construction costs would have exceeded $250K.
A spool piece was sold through our Corrosion Division that included taps to aspirate +5PSIG of air immediately after the valve.
