The basic features of cast steel ball valves: Currently, cast steel ball valves can be used in natural gas pipeline lines, oil refining facilities and nuclear industry applications in a short period of time. In addition, in other industries, regardless of large and medium-sized diameters and medium and low pressure fields, cast steel ball valves will also become the dominant valves. Its characteristic is that when referring to the flow rate, the fluctuation of the input pressure causes the fluctuation of the output pressure. The smaller the fluctuation of the output pressure, the better the performance of the pressure reducing valve, and the value of the output pressure being lower than the input pressure basically does not change with the variation of the input pressure. The working principle of cast steel ball valves: The application of cast steel ball valves is increasing year by year. In China, ball valves are used in industries such as petroleum refining, long-distance pipelines, chemical engineering, papermaking, pharmaceuticals, water conservancy, power, municipal services, and steel, playing a crucial role in the national economy. The ball valve can be tightly closed with a 90-degree rotation and a very small torque. The inner cavity of the flat valve body provides a straight-through flow path with very little resistance for the medium. It is generally believed that ball valves are suitable for direct opening and closing, but recent developments have designed ball valves to be used for throttling and flow control. The main features of ball valves are their compact structure and easy maintenance. They are suitable for general working media such as water, solvents, acids and natural gas, and are also applicable to media with harsh working conditions, such as oxygen, hydrogen peroxide, etc. To shorten the delivery time, we have cast steel ball valves in stock with diameters ranging from DN15 to DN250 and pressures from 16 to 25 kilograms. Meanwhile, other cast steel ball valves are also in stock to facilitate purchasing by users from all regions.
