- Water Supply
The ball valve is used as a shut-off valve in heat supply systems, water supply systems, in steam, fuel and pneumatic systems with compressed air and neutral gases. Installation of valves of this series is possible in systems transporting liquid and gaseous media (water, oil, oils, steam, air, alcohols, glycol, etc.), non-aggressive to the materials of the valve.
Electric quarter-turn controlled actuators DNOVA series QT are designed for remote and local control of rotation of a shut-off element by 0° ~ 270° of such types as a ball valve, etc. Application: widely used in various sectors of the national economy: in the gas, oil, metallurgy, food industry, in housing and communal services, etc.
