The number that matters
Nominal pressure
16bar
The pressure class of the valve body at 20 °C. Working limits depend on the medium and its temperature.
Construction
Parts and materials
Butterfly valves DNOVA AL-316L-EPDM are designed for use as shut-off or regulating valves for flow control in heat and water supply systems, in technological processes of food, chemical, oil and gas, pulp and paper and other industries. Butterfly valves should be installed only between collar flanges.
