The DNOVA WBV1331E-2W-F butterfly valve is designed to be used as a shut-off or control valve to control flows in heat supply systems, water supply, in technological processes in the food, chemical, oil and gas, pulp and paper and other industries. The valves are opened and closed by turning the disk 90°. Opening is done by turning the handle counterclockwise, closing - clockwise.
Quarter-turn electric actuators are designed for remote and local control of rotation of the shut-off element by 0° ~ 270° of such types as ball valves, etc.
Operating principle: electric actuators are installed directly on pipeline fittings. Installation dimensions comply with the international standard ISO 05211 / DIN3337. Four microswitches are used to limit the stroke of the output shaft by the end positions of the working element of the valve. Electric actuators are designed to operate in the nominal short-term mode S2.
