III. Working Principle of Flange Ball Valves

    A. Opening and closing mechanism

The flange ball valve has a ball type disc inside the valve body. When the valve is in the open position, the hole in the disc aligns with the pipeline direction, allowing the medium to pass through. When the valve is in the close position, the ball disc is rotated 90 degrees to stop the medium flow.

 B. Flow control and regulation

Flange ball valves provide a tight seal when closed to avoid leakage. By controlling the twisting direction of the handle, can control the direction of the ball disc, so that to control the flow rate .

VI. Maintenance and Troubleshooting of Flange Ball Valves

   A. Regular inspection and lubrication

1.Check the surface of the valve, is there any corrosion or damage. Are there any leaks, or leak risks.

2. Check the bolts and nuts which are connecting the ball valve flange and pipeline flange. Make sure they are properly torqued to prevent leaks.

3. Lubricate the valve stem regularly to ensure smooth operation and avoid corrosion.

4. Inspect the seals and gaskets, to replace them in case there are any signs of aging or damage. Keep good sealing always.

    B. Common issues and solutions

1. Leaking: First consider the seals and gaskets for damage. Replace them if necessary. Also, check the flange bolts and nuts for proper tightness. Last, check whether there are cracks on the valve body.

2. Stuck valve: If the valve is difficult to operate, check for any corrosion or foreign matter that may cause the issue. Clean the valve and lubricate it to solve the problem.

3. Valve not closing properly: If the valve is not closing properly, check the foreign matter between the ball and seats,and also alignment of the ball and seats.Clean or adjust them if necessary to ensure a tight seal.

4. Valve handle or actuator issues: If the valve handle or actuator is not working properly, check for any mechanical issues or damage. Replace or repair them if necessary.

    C. Safety precautions while handling flange ball valves

1. When handling valves, Always wear gloves and safety glasses to protect yourself from being hurt.

2. Make sure the valve is properly depressurized and the flows are stopped before doing any maintenance or troubleshooting.

3. Use tools and equipment correctly for handling or maintenance valves to avoid any accidents or injuries.

Learning More About Flanged Ball Valves

Flanged ball valves are used to shut off the flow of an operating medium that comes from both directions. This type of ball valve is designed to be simple, compact, and is usually the more economical solution when it comes to flow control applications. A flanged ball valve can be a great alternative to diaphragm valves as well as lined plug valves.

A flange ball comes with control spindle that controls the ball from the open to switching position. Once the ball is pushed by pressure against the side of the seal that is non-pressurized, the valve shuts off the flow without the risk of leakage. Ball valves cannot assume the role of a flow control valve. It can only be completely opened or closed to avoid sealing cup damages. Flanged ball valves can function correctly when they are designed to handle the right pressure and temperature in the flow system. If the flanged type ball valve does not function properly, it will lead to leakage and eventually cause corrosion to the surrounding equipment. The damage to equipment further affects the entire system, infrastructure and the environment.

Flanged ball valves are end-entry valves that come with fixed flanged connections, and provide easy operation as well as other benefits. Some of the advantages of using this device include operating at minimum pressure drop, enabling two-way flow, giving positive ?leak tight closure, and offering quick-turning operation. A flange type of ball valve can be manufactured with a durable surface paint, and can be made of a wide range of strong materials. One of the most common materials used to create them are stainless steel and lined steel. However, ball valves made from polymer materials are regarded to the superior kind because they are more durable and suitable for aggressive applications, high flow rate, combined erosion and extreme temperature. Other potential special metal compositions include alloy, chromium, titanium, and cast iron. All these materials have high resistance to not only corrosion but also abrasion.

Flange ball valves are available in different models depending on the manufacturer and the kinds of application they can perform. Reputable manufacturers subject their flange ball valve products to rigorous testing before they are offered to clients. A flanged ball valve is often used in hydraulic circuits in various industrial settings like energy supply, steel works, pipeline construction and power stations. Other facilities that typically require the use of flanged ball valve unit include wastewater treatment, chemical storage and distribution, metal treatment, pharmaceutical, mining, power generations, and agrochemicals.

High performing models of flanged ball valves are ideal in detailing with corrosive substances such as alkaline and strong acids. Most flanged type ball valve units can be installed in any position provided that the piping system follows proper fitting standards and practices. Choosing a quality and reliable flanged type ball valve unit can minimize the risk of failure. If a ball valve fails to perform its function, it results to damaging effects and at minimum, forces unplanned maintenance. This can be detrimental to the entire operation and elevate unnecessary maintenance costs.
