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.), not aggressive to the materials of the valve.
The working flow is shut off by means of a locking element, which is a ball with a through cylindrical hole. With the help of a handle mounted on the body, the ball is rotated around the axis. It is sufficient to turn it by 90 degrees to completely shut off the flow.
Electric quarter-turn actuators 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 industry, housing and communal services, etc.
