The Difference And Selection Between Full-bore Ball Valve And Reduced-bore Ball Valve

Lined Ball Valve is a mechanical product currently used in all valve markets. It is mainly composed of a valve body, a valve seat, a ball, a valve stem and a transmission device. The ball core is driven to rotate by an actuator to achieve the function of switching or adjusting. It is widely used in chemical, environmental protection, water treatment, urban construction, machinery, including food and other industries, and is very popular! Electric ball valve Pneumatic ball valve There are many types of ball valves. Through different structural forms, connection methods, pressure levels, drive forms, etc., they can be combined into various products with different functions. But basically speaking, ball valves are divided into two categories: full-bore ball valves and reduced-bore ball valves. Generally speaking, when the inner diameter of the valve ball is less than or equal to 85% of the inner diameter of the ball valve port, it is called a reduced-bore ball valve, and when the inner diameter of the ball valve is greater than 95% of the inner diameter of the ball valve port, it is called a full-bore ball valve. So what is the difference between the two when choosing or applying them?

The difference between full-bore ball valve and reduced-bore ball valve

1. Definition of full-bore ball valve and reduced-bore ball valve

A full-bore ball valve is a type of ball valve used. The ball diameter is the same as the pipe diameter, which will not affect the flow rate. Relatively speaking, the ball diameter of the reduced-bore ball valve is smaller than the pipe diameter, which is suitable for small flow media and relatively small space.

2. The structure of full-bore ball valve and reduced-bore ball valve

The full-bore ball valve has a larger appearance and is mainly composed of a valve body, a valve cover, a valve stem, a ball, a sealing ring, an operating mechanism, etc. It has good sealing performance and is usually used in large flow situations of pipelines.

The ball diameter of the reduced-bore ball valve is smaller than the pipe diameter, and the appearance is smaller. It is mainly composed of a valve body, a ball, a sealing ring, and an operating mechanism. It has a compact structure and good sealing performance, and is suitable for applications with small flow media and limited space.

3. The difference between full-bore ball valve and reduced-bore ball valve

1. Different applicable occasions

Full-bore ball valves are suitable for the transportation of large-flow media, such as pipelines in the chemical, petroleum, and natural gas industries. Reduced-bore ball valves are suitable for small-flow media and relatively small spaces, such as pharmaceutical, food, beverage, medical equipment and other application fields.

2. Different structures

The ball of the full-bore ball valve is the same as the diameter of the pipeline, and the shape is larger. It is mainly composed of valve body, valve cover, valve stem, ball, sealing ring, operating mechanism and other parts, and has good sealing performance. Relatively speaking, the ball diameter of the reduced-bore ball valve is smaller than the diameter of the pipeline, and the shape is smaller. It is mainly composed of valve body, ball, sealing ring and operating mechanism. The structure is compact and the sealing performance is good.

3. Different prices

Due to the large flow and complex structure of the full-bore ball valve during the design and manufacturing process, the cost is relatively higher. The reduced-bore ball valve is small in size, simple in structure, and relatively low in production cost.

4. 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, electric power, tap water and drainage systems. Reduced-bore ball valves are suitable for conveying and processing small-flow media, and are widely used in pharmaceutical, beverage, food and other fields. In high-demand occasions, full-bore ball valves are generally replaced by reduced-bore ball valves to make the flow more stable and prevent problems such as media leakage.
