KSB to launch new dual-function butterfly valve
KSB Group is poised for a July launch of its new shut-off butterfly valve that also functions as a check valve in seawater desalination.During normal operation, valves of the Dualis series work as electro-hydraulically actuated butterfly valves with a category A tightness to ISO 5208 / EN 12266-1. In the event of a failure, the valve will close at an adjustable speed to protect pumps, water turbines and pipelines from surge pressure and backflow.
It is manufactured in nominal sizes ranging from DN 500 to DN 1400 for pressure classes PN 6 to PN 40.
The valve has been designed for applications in water transport, water distribution, seawater desalination and hydropower as well as in industrial cooling circuits.
