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.

VIII. Conclusion
This paper discusses the key features and advantages of flanged ball valves and describes the process and methods of operation and maintenance. Their ability to handle high pressures and temperatures as well as corrosive materials, as well as their easy, flexible and fast operation, make them an important part of many industrial processes.
Looking ahead, the flanged ball valve industry is expected to continue to grow. However, there are also challenges that need to be addressed, such as improving efficiency, reducing environmental impact, and meeting changing regulatory requirements. By staying ahead of these challenges and embracing innovation, the flanged ball valve industry can continue to thrive and contribute to the success of modern industry.
A ball valve is an isolating type of valve. It is used to allow & prohibit the process media flow through the piping system. Ball valves come in different styles and are usually made of different materials. Which affects how they can be used. A flanged ball valve is a ball valve designed to have flanged ends. One can use it for shutoff applications. The usage is in hydraulic circuits. A flanged-type ball valve allows the operating fluid to flow when needed. It is very effective in providing positive leak-tight closure. For regulating or throttling purposes, a flanged-type ball valve is not suitable.
The flanged ball valve is made of carbon steel, stainless steel, or brass. These materials are perfect for tolerance to temperature and corrosion resistance. It makes them robust. This ball valve is a control component in the piping flow system. A spin of 90 degrees with a small torque is enough to close the.
Industries use flanged-type ball valves. It comes to transporting water or other liquids at low to high pressures. Flanged ball valves can start and stop the flow of fluids. It also provides the facility to change pipes without disrupting the entire line.
This type of ball valve is only different from other ball valves on the exterior. Besides the flanges, these valves contain a ball with at least two holes or ports. The standard primary ball valve has one inlet and one outlet with a hole. When rotated 90°, the hole moves vertically to the passageway and blocks the flow.
steel flanged ball valveL-type ball valves have two short bored holes and meet at a right angle in the middle. The ball can be revolved a quarter turn and connect the inlet to the outlet. When the ball rotates a quarter turn in the other direction, it will connect to a second outlet. T-type flanged ball valves have three holes, which meet in the center to form a T shape.
The current can move into both outlets or to one or the other. The ball can differ in size. A full port ball valves have a ball more prominent than the passages size, and the hole is the same diameter as the pipe. There is no flow limit for valves of this kind because the pipe walls are flush with the hole. Compact port balls have small balls with even smaller holes that make it hard to move around.
Gear Unit: The clockwise operation of a flange-type ball valve is for closure. The anti-clockwise is for the opening of the valve. It is possible by using the location indicator, which is on the side of the gear panel. Forcing the handwheel or the chain wheel alongside the stops will not provide a suitable valve shutoff and may damage the gear unit.
Actuator: The actuator controls the gear assembly and rotates the shaft. Electrically actuated valves are fixed for the manual control of the valve. The pneumatic/hydraulic actuators are fitted directly to the valve without a gear connection.
Handling:
Storage:
Before installing a Flange Ball Valve, we should concern about the following necessary steps:
To get a longer service life and maintenance-free period for flange-type ball valves, we should maintain a good temperature/pressure ratio. The following provisions should be taken while carrying out repair and maintenance of the Flange Ball Valve:
Most of the time, a ball valve is used to turn it on and off a pipe. It has solids, slurries, liquids, or gases in suspension. Ball valves are also used a lot in tubing systems, equipment, and tools used to move fluids. They are everywhere, from the factory floor to your house. Manufacturing, mining, oil and gas, agriculture, heating and cooling, plumbing, water consumer goods, construction, and other industries use it.
