Description
DNOVA butterfly valves are intended for use as shut-off or control valves for flow control in heat supply systems, water supply systems, in technological processes in the food, chemical, oil and gas, pulp and paper and other industries.
Electric quarter-turn actuators DNOVA QT2-N-xEM-O1-x-U1 with thermal protection and heater are designed for remote and local control of shut-off pipeline valves with a quarter-turn shut-off element. They are used in various sectors of the national economy: in the gas, oil, metallurgy, food industry, in housing and communal services, etc.
