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 PA-DA double-acting ball valve DN32 Ru16 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. The use of ball valves as regulating valves is not allowed.
Pneumatic actuator DNOVA PA-DA-065 double-acting rotary actuator is designed to automate the process of controlling industrial valves. It has an adjustment range of 5° when the valve stem is rotated by 90°. All internal and external parts of the pneumatic actuator are anticorrosive coated. The pneumatic actuator body is fitted with a pneumatic distributor and is designed to change the direction, start and stop the compressed air flow in the pneumatic system depending on the external control action.
