    A ball valve has a ball to control the inlet flow. The stainless steel flanged ball valve is used for control in applications to save time. The flange ball valve work by moving the valve to make the flow open blocked.

    The installation of the flanged ball is done with the following steps. When the front and back pipes should be parallel to the sealing surfaces of the two flanges, clean the pipelines of impurities in the channel. Check the flange ball valve’s symbol and the valve’s working. At both ends of the connecting flanges, remove the protective parts of the flange ball valve. The check valve is fully complete from dirt.


    In this article, you will learn the installation and keeping of flanged ball valves. Let’s explore them.

    What is a Stainless Steel Flanged Ball Valve?

    The process of joining pipes in a pipeline system is called Flange. It is the best way for connections to change, clean or inspect valves. The ball valve whose body is made of stainless steel, with the end connection of flanges, is called Stainless Steel Flanged ball valve. A flanged ball Valve is a control element for flow in the piping system to open or block the medium in the pipeline. Flanged ball valves are made of stainless steel is helpful against corrosion.

    The flanged ball valve is designed with a medium controlled by an electric actuator. It is often used in the chemical industry, petroleum, urban water supply, and drainage.


    How To Install And Use Stainless Steel Flanged Ball Valve?

    Instructions for Usage of Flange Ball Valve

    Here are some instructions you should keep in mind for the education of the ball valve. The body and disassembly of the flange end can only be out after ensuring the upstream and downstream pressure.

    You should only soak non-metal parts for a short time in the washing agent and take them out after cleaning. You can use a compatible cleaning agent, as are plastic parts, rubber parts, and an active medium. For metal parts, when the working medium is fuel gas, you can use gasoline as a washing agent. You can use alcohol or pure water to cleaning of non-metal parts.

    If the parts have degraded, every component must clean by soaking cleaning agents. Cleaned other pieces with a fine silk cloth to prevent them from attaching to the elements. Please don’t soak the parts in cleaning agents for an extended period because they will get rusted. Remove dirt, dust, grease, and glue from sticking to the wall.

    While disassembly the flange ball valve, non-metallic parts prevent damage to the part’s surface, it would help if you used particular tools for drawing the O-ring.

    Remove the cleaning agent from the parts before joining the valve to create it dry to clear all dust. Before assembly, new parts must also be cleaned and lubricated with grease. It would help if you used oil compatible with plastic parts and operating media.

    Ensure you should use metal debris, grease, dust, and other impurities from entering the hole of the valve.

    Preparations before Installation

    The front and back pipes and sealing surfaces of flanges must be parallel to the flange ball valve. The pipeline can hold the weight of the flange end and must have proper support. Proper care of the pipeline before and after installation to remove welding slag and oil.

    Use the valve to check the sign of the flange ball valve that is complete. Also, ensure the valve works appropriately by opening or closing it frequently. Remove the protecting parts installed on the sides of the stainless steel ball valve.

    Remove any dirt or impurities by cleaning the stainless Steel Flanged Ball Valve because any small particle in the valve seat may damage the sealing of the flanged ball valve.

    Flange Ball Valve Installation

    Here are some steps you must follow while installing the flanged ball valve. You must install the flange ball valve on the pipeline as needed in your system.

    You should install the valve can be in the upstream or end directions. But the actuated Steel Flanged Ball valve must install above the pipe. Install a gasket according to the need to fill the space between the pipe’s Flange and the valve’s Flange.

    The flange end ball valve moved by a handle and driven by a gearbox should be installed vertically. The bolts on the flanges must fix or tighten evenly or symmetrically. In the condition of a pneumatic-driven Ball Valve, join the pipeline at the end.

    What needs to do after installation?

    After Installation

    Operate the valve with a moving process most of the time by opening and closing the flange ball valve. The operation should be flexible and confirm that the valve is working correctly.

    Ensure that the gasket is perfectly installed and the flanges are tight as needed. Check the flange joint between the flange ball valve and the pipeline. Check sealed according to the design needs of the channel.

    What should we pay attention to when using a ball valve?

    In this section, you should consider some points when using a ball valve for the correct process.


    Proper attention should be to whether the medium is used for working steel ball valves.

    Soft or hard seals can be selected according to the type of liquid when the medium is liquid. It would be best if you suggested using a soft seal when the medium used is gas. If the medium is corrosive, you must use anti-corrosion fluorine lining materials should be used instead.


    You also pay attention while using the stainless steel ball valve. Check what type of working temperature medium need for ball valve parameters. Hard sealing and high-temperature materials must be used when the temperature is more than 180°C. High-temperature materials should take when the temperature is higher than 350°C.

    Pressure is the most typical issue of the stainless steel ball valve. Generally, many people suggest that the pressure level should be higher. For instance, you should use the pressure level 1.6MPa, if the operating pressure is 1.5MPa. Higher level pressure can provide the safety performance of the pipeline during use.


    In the process, you should use some mining and on-site industrial needs. You should use a medium having sand, gravel, hard particles, slurry, lime, and another sample. It would be best if you used ceramic seals. If ceramic seals can not solve the problem, use them instead of ceramic.


    How Should We Maintain The Stainless Steel Flanged Ball Valve?

     Keeping temperature pressure and media will provide longevity to the flange ball valve.

    It would help if you kept in mind the following precautions while taking out care of it. If you use the valve sparingly, then cycle the valve once a month or more. Release the pressure line and operate the valve in the open position before working the valve.

    There is fluid under pressure inside the valve body, so note even after closing the flange ball valve. Before repairing the flange ball valve, disconnect the air supply from the driving. In maintenance, disconnect the actuator from the bracket. Also, relieve the system pressure before maintaining the valve.

    Before disassembly, release only the upstream and downstream pipelines of the flange ball valve.

    Replace valve seals and seats by pulling the end plates. With the ball in the closed position, press carefully pushes out the ball and end seats. Stop damage to the polished ball surface using a soft clean cloth to hold it. Seals push the drive stem inside the cavity to reveal the branch. Reinstall the seals, ball, seats, and end plates. Use only authorized lubrication on the seals. Test and refit into line as in the installation series.

    The flanged ball valve is corrosion-resistant to the other Ball Valves. The sealing surface of flanged ball valves is often closed and corroded by the medium. So they are stainless Steel Flanged Ball Valves widely used in various industries. The effects of having flanges made the Stainless Steel Flanged Bal Valve has made it easier to use. It can be helpful in fast replacing a valve in a pipe system.

    The Stainless Steel Flanged Ball Valve can handle High-Pressure. The stainless Steel Flanged Ball Valves have high-pressure level than the other valves. All above you have learned in detail about flanged ball valves. If you have any questions feel free to contact us today.
