A stainless steel ball valve is a reliable and versatile device for controlling the flow of liquids and gases in various industrial sectors. Made from corrosion-resistant stainless steel, it possesses high strength and can withstand both high temperatures and pressures. Ball valves are easy to operate, provide secure sealing, and minimize the risk of leaks, making them an ideal choice for use in the oil and gas industry, water treatment plants, the food industry, and other areas where a reliable and durable valve is needed to regulate the flow of substances.
Ball valve DNOVA BV3232P-FP-Fb-ISO-H QT-EX-EM-O2-24VDC-U1 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.), not aggressive to the materials of the valve. The use of ball valves as regulating valves is not allowed.
Electric actuators of explosion-proof version QT-EX-EM-O1-24VDC-U1 are used in industrial explosion hazardous areas to control butterfly valves, ball valves and other quarter-turn valves with ambient temperature -20...+60°C.
