وصف
Butterfly valves DNOVA are designed for use as shut-off or regulating valves for flow control in heat supply systems, water supply systems, in technological processes of food, chemical, oil and gas, pulp and paper and other industries. Butterfly valves should be installed only between collar flanges.
Electric quarter-turn actuators DNOVA are designed for remote and local control of shut-off pipeline valves having a quarter-turn shut-off valve. They are used in various branches of national economy: in gas, oil, metallurgical, food industries, housing and utilities, etc.
