Double-seat valves
VARIVENT® Mixproof shut-off valves, piggable
A special feature of this valve is that the pig can be conveyed through the cylindrical design of the housing. Pigging technology enables valuable products to be recovered at the end of the process step, thereby minimizing product residues in the pipe.
