                          • The BKG Polygon™ water filtration system is an automated, self-cleaning tempered water system which minimizes operator intervention to help maximize productivity and reduce energy consumption in order to increase operating profit. It is suitable for compounding, polymerization and recycling applications.
                          • BKG® Polymer Diverter Valve

                          • The polymer diverter valve consists of a heated housing and a hydraulically movable piston. By hydraulic actuation of the piston, the melt flow can be diverted towards the floor or directed towards the die plate.

                            The diversion is necessary because the desired optimal melt flow per die plate hole cannot be generated instantaneously by the preceding equipment (e.g. extruder) at start-up.

                            The polymer diverter valve also separates the pelletizing process from the preceding process (e.g. extruder) so that both can be shut down separately in case of minor faults or changes made at the pelletizer.
                          • EDI™ Strand Dies

                          • EDI strand dies for plastic pelletizing are designed to provide uniform pellets of resin following its extrusion through a strand die face. Whether virgin or reclaimed material, once the resin is extruded and cooled, the strands are cut at a very high speed yielding pellets of a prescribed size for optimal processing in manufacturing environments.
                          • BKG® Tempered Water Systems

                          • To meet customer requirements, Nordson designs BKG water systems with modularity in mind. Each component can be installed individually, thus changes in the equipment line-up are accomplished quickly and easily to suit product requirements.
                            The most basic version of the system contains the pellet dryer and water tank with accessories for simple processes such as non-filled polyolefins.
                          • BKG® WRP-12i In-Line Pelletizers

                          • Nordson's BKG water ring pelletizer connects directly to the end of the extruder, screen changer or gear pump via a short coupled adapter allowing polymer to flow horizontally from the extruder to the in-line die plate.

                            The rheologically optimized design minimizes polymer inventory between the extruder and die plate and evenly distributes polymer flow to each die plate hole. The result is a consistently uniform pellet.

                            Reclaim, masterbatch, and compounders will benefit by improved pellet quality during both short and extended production runs.
                          • BKG® WRP-35s/36s Pelletizers

                          • Nordson's BKG water ring pelletizing systems offer a modern, cost-effective method of pelletizing a wide range of unfilled and filled thermoplastic polymers.

                            The water ring hot die face ensures a consistent, uniform pellet and is insensitive to short term polymer flow interruptions. Pellets are cut and immediately quenched in a unique cooling chamber design that transfers the pellet slurry to the spin dryer. An integral dryer blower is standard for improved drying efficiency. Typical applications include polymer reclaim, compounding, color concentrates and polymerization.
                        • Polymer Valves

                        • For the economic operation of complex lines, a polymer valve, which regulates the melt flow in a controlled manner or discharges the material out of the running process, becomes necessary.

                            • BKG® HyFlex™ 3/3-Way Valves

                            • Depending upon the position of the valve the polymer can be directed through different inlets and outlets to guide the melt into the appropriate flow channels. The BKG 3/3-Way valve is suitable for switching between two production processes (e.g., switching of two large area filters). The melt may optionally be guided into one or both outlet channels. Switching between the two outlet channels is done without pressure variation and without trapped air.

                            • BKG® HyFlex™ Multiport Valves

                            • Distribution of one product stream to multiple strands or merging of multiple streams to one strand. During operation one or more of the outlet valve pistons are enabled or disabled providing the correct structure to enter the downstream components.
                            • Pellet Diverter Valve

                            • The pellet diverter valve is a pneumatically operated valve that is mounted at the dryer outlet and allows for the switching between two pellet discharge chutes for the purpose of a.) gaylord changeover, b.) elimination of low quality pellets during start-up, or c.) sampling of pellets during production.

                            • The BKG shut-off valve interrupts the melt flow in the system. It is suitable for multiple layer film lines and reactor processes.

                              It enables a controlled start-up / shut-off of the melt flow (maintenance, interruptions, etc.).

                            • BKG® HyFlex™ Start-up Valves for Underwater Pelletizing Systems

                            • There are a number of reasons to use a diverter valve when operating an underwater pelletizing system.
