Description
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.
Explosion-proof quarter-turn electric actuators are designed for remote and local control of the rotation of a shut-off element by 0° ~ 270° of such types as a ball valve, etc. They are widely used in various sectors of the national economy: in the gas, oil, metallurgy, food industries, in housing and communal services, etc. They are suitable for use in industrial explosion-hazardous areas.
