PSI - Model DIV -Diverter Valve
PSI Diverter Valves (DIV) direct the flow of a fluidized material stream to a selectable destination. Used in polymer, hot melt adhesive, food, and chemical applications, diverter valves are commonly supplied in a two-position (process/dump) configuration to facilitate start-up, drum-fill operations, or redirection to a secondary process. For pelletizing operations, the dump position segregates start-up materials, including off-spec generated during crossover for material or color changes. Once the material flow and quality are fully established, a quick shift to the online position assures optimal pressure and flow to the die. For drum or vessel fill operations, the dump position is used for bypass.
Multiple (three or four) position diverter valves add bypass and multi-directional flow functionality. Applications for these include alternating die and simultaneous multi-die flow as well as bypass or tank fill. Discharge ports can be configured to accommodate virtually any direction. These diverter valves offer vertical and rotational port movement. Sizes range from small batch operations to large polymer reactors requiring continuous output.
