20` Titanium Slurryflo Control Valves - Case Study
With an analysis of the process conditions and modulating history, SlurryFlo’s engineering team developed a unique ‘dual purpose’ trim (see Fig 3). As the gate opens, it exposes two small ceramic orifices to vent steam (see Fig 4). Once the flash vessel has been vented, the gate can be retracted further if additional flow is required (see Fig 5). Note that flow is centered within the pipe in both scenarios.
Upon replacing their Titanium butterfly valves with SlurryFlo control valves, the client quickly realized a return on investment. During the first inspection (1 month post installation), the maintenance team observed minimal erosion on the wear components. As the downstream piping also remained in excellent condition, it was decided to operate the valves for several months between inspections. After 12 months of continuous service, the valve trims are replaced and the valves are reinstalled.
