With their constant processing design, CSC type continuous screen changers are able to meet the most stringent quality requirements for melt filtration. The type HSC, FSC and DSC discontinuous screen changers are a simple, robust, and affordable alternative for applications where a short interruption in the melt flow is possible for making screen changes.
The DV continuous divert and dump valve was developed specifically to meet the requirements of underwater pelletizing. It features a unique design that provides bump-less changeovers and eliminates the possibility of a deadhead condition.
