  • Large DN Size Oxygen Ball Valve

    Large DN Size Oxygen Ball Valve

    LYV®️ large DN size oxygen ball valve is a special valve specially designed for oxygen pipe network, which is widely used in the pipe network of steel, metallurgy, petrochemical, chemical and other oxygen-using projects. In addition to the functions of ordinary valves, it also has its own characteristics such as good flame retardancy, good electrical conductivity, fast heat transfer, compact structure, oil resistance, safety and reliability. Strict oil prohibition measures are adopted during manufacturing, and all parts are subjected to strict degreasing treatment before installation. All diameter valves are equipped with conductive screw holes at the flange ends to prevent static electricity. The exposed parts of the valve have protective measures to prevent dust and oil pollution. With the valve seat of the metallurgical industry, the special oxygen ball valve and the special oxygen stop valve are widely used in steel, medicine, chemical and other industries.

  • Reasons for Valve Leakage and Solutions

    Leakage Caused by the Falling Off of Closing Part Reasons: Poor operation causes the closing part to jam or exceed the top dead center, damaging or breaking the connection. The closing part connection is not secure, leading to loosening and falling off. The selected connection materials are unsuitable and cannot withstand the corrosion of the medium or mechanical wear.

  • What does the arrow marked on the valve body mean?

    The arrow marked on the valve body indicates the recommended pressure-bearing direction of the valve, not the direction of the fluid flow in the pipeline. For valves with bidirectional sealing capabilities, the arrow may or may not be marked. If marked, it points to the recommended pressure-bearing direction, as one of the two possible directions—either horizontal or vertical—will usually offer better performance.

  • What are the characteristics of ball valves?

    Pneumatic ball valves have a simple and compact structure, reliable sealing, and easy maintenance. The sealing surface and spherical surface are often in a closed state, which is not easily eroded by the medium and is easy to operate and maintain. They are suitable for general working media such as water, solvents, acids, and natural gas. They are mainly used to cut off or connect media in pipelines, and can also be used for fluid regulation and control.

  • How does a ball valve work?

    The working principle of a ball valve is to control the flow of fluid by rotating the ball. The main components of a ball valve include the ball body, valve seat, valve stem, and handle. When the handle rotates, the valve stem drives the ball to rotate, thereby changing the shape of the channel inside the valve body and achieving fluid on/off control.

  • Demystifying Industrial Valves: Types and Applications

    In the intricate realm of industrial processes, where the precise regulation of fluid flow and pressure is paramount, valves emerge as the unsung heroes. These electro-mechanical devices play a pivotal role in controlling, directing, and regulating the movement of fluids within complex systems. Let's delve deeper into the world of industrial valves, exploring their types and diverse applications.
