Discover our solution that boosts the reliability of the AL and BL heavy-duty rotary valve series (including AXL, BXL, BXXL and NR) even more: the DMN-WESTINGHOUSE Shaft seal flow control. This flow control system ensures a consistent and controlled airflow, even in the face of pressure variations, to protect the shaft seals and prevent wear, ultimately contributing to the reliability and performance of your equipment. Unlike pressure, airflow can be monitored precisely to register blockages or leaks. Flow control is the go-to solution for CIP processes. On top of that, accurate flow control prevents the build-up of powder residue on the shaft seals that could lead to seal failure, causing contamination, leakage, damage, and downtime for cleaning and repair.
