    Butterfly Valve-FAQ

    1. What is a butterfly valve?

    Butterfly Valve is a type of throttling valve, which is an important device in water supply and drainage piping system. It is designed to allow the valve flap (usually in the shape of a disk, similar to the wings of a butterfly) to rotate in the pipeline, thus controlling the flow of fluid. Butterfly valves are usually used in large-diameter pipelines and are popular for their simple structure, lightweight operation and easy maintenance.

    2. What are the main advantages of butterfly valve?

    The main advantages of butterfly valves include simple structure, small size, light weight, low operating torque, quick opening and closing and labor saving. In addition, butterfly valve has less fluid resistance, can be applied to larger caliber pipeline, and has better flow control performance.

    3. What are the applicable scenes of butterfly valve?

    Butterfly valves are usually applied to low-pressure, large-diameter piping systems, such as water supply, drainage, sewage treatment, ventilation and air conditioning projects. They are especially suitable for occasions where frequent switching or flow adjustment is required, as they can be opened or closed quickly and easily.

    4. What are the choices of materials for butterfly valves?

     The materials of butterfly valves can be selected according to the application requirements, and the common ones are cast iron, cast steel, stainless steel, copper alloy and so on. For the occasions that need to withstand higher pressure and temperature, generally choose the stronger and heat-resistant material.

    5. How to judge the sealing performance of butterfly valve?

    The sealing performance of butterfly valve is one of the important indexes of its quality. Usually, it can be judged by checking whether the contact surface between the valve flap and the valve seat is flat, and whether there is any wear or corrosion. In addition, in actual use, if there is still leakage after the valve is closed, it may indicate poor sealing performance.

    6. What do I need to pay attention to when installing and using butterfly valves?

    When installing butterfly valves, it should be ensured that the valves are tightly connected to the pipeline without leakage, and the appropriate installation position and angle should be selected according to the actual situation. In the process of use, the operation of the valve, sealing performance and the wear and tear of each part should be checked regularly, and any abnormality should be dealt with in time.

    7. How to choose a suitable butterfly valve?

    Selection of a suitable butterfly valve needs to consider several factors, including the caliber of the pipeline, working pressure, the nature of the medium and the use of requirements and so on. In addition, it is also necessary to consider the material of the valve, sealing performance, operating torque, and other performance parameters. It is recommended to consult with professionals or manufacturers when choosing to ensure that the selected valve can meet the actual needs.
