    What is Screwed Ball Valve

     

    Screwed Ball Valve is a fluid control device commonly used in pipeline systems, mainly used to control the opening and closing of fluids in pipelines. Its working principle is to change the flow direction or on-off of the fluid by rotating the ball. The threaded ball valve is characterized by being connected to the pipeline through a threaded connection, easy to install, and suitable for small-diameter pipelines.

     

    Advantages

    1. Multiple material options
    Threaded ball valves can provide multiple material options according to the specific needs of users. Common materials include stainless steel (such as SS304, SS316, SS316L), copper alloy, carbon steel and plastic (such as PVC, PVDF, etc.). For example, stainless steel is suitable for high temperature and corrosion-resistant environments; while PVC is more suitable for low pressure and fluids with milder chemical properties.

     

    2. Strong sealing
    The threaded ball valve has excellent sealing performance, thanks to the close contact between the ball and the valve seat. When the valve is closed, a perfect sealing surface is formed between the ball and the valve seat, which can effectively prevent leakage. Even in high-pressure and high-temperature working environments, threaded ball valves can still maintain good sealing and are suitable for applications with high sealing requirements.

     

    3. Customizable service
    The first is pressure level customization. According to the actual working environment requirements, threaded ball valves can be customized with different pressure levels, from low pressure (such as PN10) to high pressure (such as PN40), to ensure that the valve can withstand the required pressure conditions.

     

    The second is the customization of sealing materials. According to the characteristics, temperature and pressure requirements of the fluid, users can choose different types of sealing materials, such as PTFE, FPM, NBR, VITON, etc. These materials can meet the needs of special working conditions such as high temperature, high pressure and chemical corrosion, ensuring that the valve works normally in harsh environments.

     

    Finally, the diversity of connection methods. In addition to the common threaded connection, the threaded ball valve also supports flange connection, clamp connection, welding connection and other connection methods. It can be compatible with different types of pipeline systems and adapt to different installation requirements.

Stainless steel, carbon steel, alloy steel and other materials are widely used in the manufacture of threaded ball valves due to their high strength and good corrosion resistance. Different materials have different adaptability to the medium, and factors such as the nature, temperature and pressure of the medium should be considered when selecting. The ball is a key component of the ball valve, and its material must match the valve body to ensure sealing and corrosion resistance. The choice of sealing material is equally important, which determines the sealing effect of the valve in the closed state.
    Manufacturing process: The quality of the manufacturing process directly affects the processing accuracy and surface quality of the valve, which in turn affects the sealing performance and durability of the valve. High-quality manufacturing technology can ensure that the various components of the valve are closely matched, reducing leakage and wear.
    Operation frequency: Frequent operation of the valve will increase its wear and fatigue, thereby affecting durability. Therefore, the operation frequency of the valve should be considered during design and use, and a reasonable maintenance plan should be arranged.

    Q: Will screwed ball valve rust?

    A: The material of the screwed ball valve has a direct impact on its rust resistance. If the ball valve is made of corrosion-resistant materials such as stainless steel, its rust resistance will be relatively good. However, if the material is not properly selected or the quality is poor, the ball valve is more likely to rust in a humid and corrosive environment.

    Q: Why use screwed ball valve?

    A: Easy to install and connect: The screwed ball valve adopts threaded connection, which makes installation and disassembly very simple and quick. Users can easily complete the installation work without complex tools or professional skills.
