Stainless steel ball valve is used as a shut-off valve in heat and water supply systems, 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.) that are non-aggressive to the materials of the valve.
