Description
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 open and close by turning the disk 90°. Opening is done by turning the handle counterclockwise, closing - clockwise.
Explosion-proof 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 a ball valve, etc. They are widely used in various sectors of the national economy: in the gas, oil, metallurgy, food industries, in housing and communal services, etc. Suitable for use in industrial explosion hazardous areas.
