Construction
Parts and materials
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.
Pneumatic valve DNOVA 4V320-08 220V is used to change direction, start, stop compressed air flows in a pneumatic system depending on external control action.
