Ball valves are used as shut-off valves in heat and 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 valve materials.
Pneumatic actuator DNOVA pneumatic double-acting rotary actuator PA-DA-105-1 with hand wheel is designed for automation of industrial valve control process, as well as for determining the position of the valve shut-off body.
