Discover our solution that boosts the reliability of AL and BL high-duty rotary valve series (including AXL, BXL, BXXL and NR) even more: the DMN-WESTINGHOUSE Shaft seal flow control. This flow control system is designed to create an ever-stable airflow to the rotor shaft seals, generating a continuous overpressure compared to the line pressure. Unlike pressure, airflow can be monitored precisely to register blockages or leaks.
With flow control, your system will be less prone to pressure variations, making it 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 contamination, leakage, damage and downtime for cleaning and repair.
The Shaft seal flow control is designed for our high-duty AL and BL range rotary valves with a size of 150 to 350. The airflow system is available for new valves and can easily be retrofitted on existing valves.
