Description
Butterfly valves are designed for use as shut-off or regulating valves for controlling flows in heat supply systems, water supply systems, in technological processes of food, chemical, oil and gas, pulp and paper and other industries. The valves are opened and closed by turning the disk by 90°. Opening is performed by turning the handle counterclockwise, closing - clockwise.
Electric quarter-turn actuators controlled by DNOVA QT series are designed for remote and local control of 0° ~ 270° rotation of a shut-off valve of such types as ball valves, etc. They are widely used in various branches of national economy: in gas, oil, metallurgical, food industry, housing and communal services, etc.
