Diverter Valve (DIV)

Get More from Your Process

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 operations.  The dump position segregates off-spec start-up materials, including those 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 volumetric flow to the die. This eliminates the potential for die hole freeze-off, off-spec pellets and cross-contamination of degraded start-up material in the pellet dryer typically encountered in systems without divert capability.

Three, four and five position diverter valves add bypass and multi-directional flow functionality. Applications for these include alternating die and simultaneous multi-die flow as well as die 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.
