The ball valve is used as a shut-off valve in heating, water supply, 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. The use of ball valves as regulating valves is not allowed.
DNOVA pneumatic double-acting rotary actuators PADA are designed to automate the process of controlling industrial valves with maximum torque up to 2128 Nm.
