Design
DUALIS is a shut-off butterfly valve, which also functions as a check valve.
It is manufactured in nominal sizes ranging from DN 500 to DN 1400 for pressure classes PN 6 to PN 40. It’s composed of a counter weight and a butterfly valve
During normal operation, Dualis works as electro-hydraulically actuated butterfly valves.
It opens when the arm is lifted thanks to an hydraulic jack supplied by an hydraulic power unit. In the event of failure, the weight fitted to the lever arm falls and closes the valve.
Application
Pumps, turbines, pipelines protection
Prevention of fluid backflow
