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 valve materials. The use of ball valves as control valves is not allowed.
Electric actuators are installed directly on pipeline fittings. The installation dimensions correspond to the international standard ISO 05211 / DIN3337. Four microswitches are used to limit the stroke of the output shaft according to the end positions of the working element of the fitting. Electric actuators are designed for operation in the nominal short-term mode S2.
