Description
Ball valves are used as shut-off valves 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.
The shut-off of the working flow occurs by means of a locking element, which is a ball with a through cylindrical hole. The handle installed on the body rotates the ball around the axis. To completely shut off the flow, it is enough to turn it by an angle of 90 degrees.
Quarter-turn electric actuators are designed for remote and local control of shut-off pipeline valves with a quarter-turn shut-off element. They are used in various sectors of the national economy: in the gas, oil, metallurgy, food industries, in housing and communal services, etc.
