Description
Butterfly valves are designed to be used as shut-off or control valves for managing flows in heating systems, water supply systems, and technological processes in the food, chemical, oil and gas, pulp and paper, and other industries.
Quarter-turn electric actuators of the DNOVA QT series are designed for remote and local control of the rotation of the shut-off element from 0° to 270°, for types such as ball valves, etc. They are widely used in various sectors of the economy: gas, oil, metallurgy, food industry, housing, and utilities, etc.
The electric actuators are installed directly on pipeline fittings. The installation dimensions comply with the international standard ISO 05211 / DIN3337. Four micro switches are used to limit the stroke of the output shaft at the end positions of the working element of the fittings. The electric actuators are designed to operate in an intermittent duty cycle S2.
