The difference between full bore ball valves and reduced bore ball valves
The difference between full bore ball valves and reduced bore ball valves
Full bore ball valves and reduced bore ball valves are two common types of ball valves. The ball diameter of the full bore ball valve is the same as the pipeline diameter, and is suitable for the transportation of high flow media, such as transportation pipelines in industries such as chemical, petroleum, and natural gas. Reduced diameter ball valves, on the other hand, have a smaller diameter than pipeline diameters and are suitable for applications in small flow media and relatively small spaces, such as pharmaceuticals, food, beverages, medical equipment, and other fields. The full bore ball valve has a complex structure and high cost, while the reduced bore ball valve has a small volume, simple structure, and relatively low price.
1、 Definition of full bore ball valves and reduced bore ball valves
Full bore ball valve is a widely used ball valve model, with the same ball diameter as the pipeline diameter, which will not affect the flow rate. Reduced diameter ball valves, on the other hand, have a smaller diameter than pipelines and are suitable for small flow media and relatively small spaces.
2、 The structure of full bore ball valves and reduced bore ball valves
The full bore ball valve has a larger appearance and is mainly composed of valve body, valve cover, valve stem, ball, sealing ring, operating mechanism, etc. It has good sealing performance and is usually used in high flow situations of pipelines.
The spherical diameter of a reduced diameter ball valve is smaller than that of a pipeline, with a smaller and more compact appearance. It mainly consists of a valve body, spherical body, sealing ring, and operating mechanism. Compact structure, good sealing performance, suitable for small flow media and limited space applications.
3、 The difference between full bore ball valves and reduced bore ball valves
1. Applicable occasions vary
Full bore ball valves are suitable for the transportation of high flow media, such as pipelines in industries such as chemical, petroleum, and natural gas. Reduced bore ball valves are suitable for small flow media and relatively small space applications, such as pharmaceuticals, food, beverages, medical equipment, and other fields.
2. Different structures
The ball of a full bore ball valve has the same diameter as the pipeline, and has a larger shape. It mainly consists of the valve body, valve cover, valve stem, ball, sealing ring, operating mechanism, and other parts, with good sealing performance. Reduced diameter ball valves, on the other hand, have a smaller diameter than pipeline diameters and a more compact appearance. They mainly consist of valve bodies, spheres, sealing rings, and operating mechanisms. Compact structure with good sealing performance.
3. Different prices
Due to the large flow rate and complex structure of full bore ball valves during the design and manufacturing process, the cost is relatively higher. The reduced diameter ball valve has a small volume, simple structure, and relatively low production cost.
4、 The application of full bore ball valves and reduced bore ball valves
Full bore ball valves are suitable for conveying and processing large flow media, and are commonly used in petrochemical, power, tap water, and drainage systems. Reduced diameter ball valves are suitable for conveying and processing small flow media, and are widely used in fields such as pharmaceuticals, beverages, and food. In high demand situations, full bore ball valves are generally replaced by reduced bore ball valves to ensure smoother flow and prevent medium leakage and other issues.
