How it works
Electric quarter-turn actuator
Butterfly disc
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
DNOVA butterfly valves are designed for use as shut-off or regulating valves for flow control in heat supply systems, water supply systems, in technological processes of food, chemical, oil and gas, pulp and paper and other industries.
The DNOVA QT series electric actuator allows remote control of the gate and solving a wide range of automation tasks.
