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.
The ball valve DNOVA is used as a shut-off valve in heat and 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 valve materials.
Double-acting pneumatic rotary actuators and pneumatic rotary actuators with return springs are designed for automation of control process of industrial shut-off valves - gates, ball valves. DNOVA pneumatic actuators are designed for operation both indoors and outdoors. All internal and external parts are anticorrosive coated.
Manual doubleturn actuator with disengageable clutch DNOVA BV3232P(3pc)-FP-W-ISO-H Ru63/40/25 PA-DA MON allows to manually set the required positioning of valves, dampers and other quarter-turn devices when replacing pneumatic, electric or hydraulic quarter-turn actuators. Suitable for both indoor and outdoor installation. The modular design of the manual override is intended to provide the most efficient and effective solution to the full range of manual override applications.
