What is ball valve?
A ball valve is a type of 90 degree shut-off valve, primarily used to control flow rate. It is a quarter-turn device. It allows for safe and convenient control of gas or fluid. When the handle is in a parallel position, it indicates a flowable state; when the handle is vertical, it is in the closed state.
ball valve Type By Design
Floating Ball Valve
The floating ball valve features an automatic sealing capability. Its primary structural characteristic is an anti-blowout stem design; specifically, when the fluid medium flows through the valve, the pressure within the valve body cavity could potentially force the stem outward.
Trunnion Mounted Ball Valve
The Trunnion Ball Valve is manufactured in compliance with the API 6D standard, and its body material is ASTM A105. Its connection type conforms to the EN 1092-1 Type D standard.
ball valve Type By Bore
Full Bore Ball Valve
The primary characteristic of a full-bore ball valve is that pressure drop is minimal when the valve is open, thereby ensuring excellent flow of the medium.
Reduced Bore Ball Valve
A Reduced Bore Ball Valve is a compact quarter-turn valve. It is frequently utilized in piping sections where one port features a larger diameter than the other. Offering excellent sealing performance, it is commonly employed for connecting branch lines within piping.
ball valve Type By Material
Stainless Steel Ball Valve
The primary characteristics of stainless steel ball valves are corrosion resistance and rust prevention. Their nominal pressure range is 1.6 to 40 MPa, and their applicable temperature range is 100 to 400°C.
Cast Steel Ball Valve
The cast steel ball valves manufactured by our company are flanged ball valves that comply with various standards, including GOST 9544, the American standard API, the German standard DIN, and the Japanese standard JIS.
Ball Valves Type By Construction
Two-Piece Ball Valve
Two-piece ball valves typically consist of a main valve body and a secondary valve body. This type of valve is easier to disassemble for inspection.
Three-Piece Ball Valve
A three-piece ball valve typically consists of a left valve body, a middle valve body, and a right valve body. Its manufacturing standard is API/ANSI. It is suitable for some large-diameter piping systems.
Ball Valves Type By End Connection
Flanged Ball Valve
Flanged ball valves are a type of quarter-turn shut-off valve, widely utilized in industrial pipelines within sectors such as the petroleum and chemical industries. They serve the function of opening and shutting off flow, offering high sealing integrity as well as resistance to high pressure and high temperatures.
Butt Weld Ball Valve
The connection method for butt-welded ball valves is welding. This is a commonly used method in industrial valves, but this welding method makes disassembly difficult later.
Threaded Ball Valve
Threaded ball valves utilize a threaded connection and are predominantly small-bore valves. Their key features include a compact structure, excellent sealing performance, structural simplicity, and ease of maintenance.
When to Choose a Ball Valve?
There are many types of valves, and choosing the right one is an essential aspect for technicians. Here are some common reasons for choosing ball valves:
1. Need for rapid valve operation: In your designed piping system, where frequent valve opening and closing is required, ball valves are a good choice because they only require rotation to operate.
2. High sealing requirements: Ball valves offer high sealing performance, whether floating or fixed. Their sealing performance remains unaffected even after prolonged periods of inactivity.
3. Low resistance: When fully open, a ball valve matches the pipe diameter, resulting in almost no resistance. This ensures excellent flow rate.
4. Frequent disassembly and cleaning of pipelines: In some industries, regular maintenance and cleaning of the piping system may be necessary. In such cases, ball valves are the best choice.

How to Select Floating Ball Valve?
When selecting ball valves, consider the following:
1. Ball valve manufacturing standards: Choose the appropriate pressure rating, operating temperature, and material based on actual usage requirements.
2. Ball valve design structure: Is it full-bore or reduced-bore? Or, in certain systems, is an anti-static device required?
3. Safety level: Consider its sealing performance over long-term use, and whether the operation is manual, electric, or pneumatic.

Ball Valve Engineering Design and Solutions
Some products require adjustments, therefore manufacturers must plan and design. Operators can ensure that products meet relevant requirements and standards.
Base Materials
Manufacturers need to use raw materials according to requirements. Since the raw materials required for some products may differ, raw materials need to be stored separately to prevent misuse.
Forging and Cutting
Ball valves come in different sizes depending on the application. Valves require high-temperature heating during forging and cutting to achieve the desired shape. Forged ball valves are robust, durable, and have excellent sealing properties, effectively preventing leaks, making them the preferred choice for most industries.
Trimming
To manufacture ball valves with the correct shape, manufacturers use trimming dies to remove burrs and flash from the rough valve body.
Sandblasting
Rough parts on the valve body can be removed using a sandblasting machine, resulting in a smooth and clean valve surface.
CNC Machining: CNC machine tools and multi-axis machine tools can obtain the correct threads and dimensions according to the ball valve's technical drawings. This is a crucial step in ensuring product quality and an important means of verifying product compliance with standards.
Surface Treatment: Manufacturers must comply with government-mandated environmental regulations. Therefore, products need to be treated to ensure they do not harm the environment.
Assembly: The next step is assembly. You must assemble the various valve components onto the valve body on the production line. These components are hand-manufactured and assembled as a single valve unit.
Qualitative Testing: Each ball valve will undergo quality testing to ensure it is leak-free. For this purpose, the valve will be placed in pressurized air at 6 to 8 bar for 24 hours.
The testing cycle depends on the valve size. Larger valve sizes require longer testing cycles; smaller valve sizes require shorter testing cycles. After testing, it is essential to check the valve for leaks.
Transportation and Packaging: Operators inspect the finished ball valves before packaging. At this point, the product is ready for delivery.
The above steps are the general process for ball valve manufacturing. To improve and produce higher-quality products, different manufacturers may add extra steps. Consulting with the manufacturer for further information is the best approach.
