  • What are the Advantages of Floating Ball Valve Compared with Other Valves?

    The key to floating ball valve is that its ball has no fixed shaft support running through it. When the valve is closed and needs to be sealed, it is the pressure generated by the liquid or gas flowing in the pipeline that pushes the ball tightly against the sealing surface.

  • The Critical Role of High-Performance Butterfly Valves

    A U.S. Environmental Protection Agency study shows that fugitive emissions from damaged industrial valves cause more than 300,000 tons of volatile organic compounds to leak each year, equivalent to 64 million gallons of gasoline. Factory engineers confirmed that butterfly valve failures accounted for 59% of all failures during the five-year operating cycle. LYV® is committed to developing precise flow control solutions that turn this critical weakness into the most reliable component in your system.

  • How Do You Select the Perfect Butterfly Valve for Your Application

    The choice can mean the difference between a system that runs seamlessly for years and one plagued by downtime, leaks, and costly maintenance. Among the most versatile and widely used options is the Butterfly Valve. Its simplicity, reliability, and cost-effectiveness make it a staple, but not all butterfly valves are created equal. At LYV, we’ve dedicated our expertise to engineering valves that aren’t just components, but foundational pillars for your system’s integrity and efficiency. Let’s navigate the key considerations together, from the ground up.

  • 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.

  • Ideal choice for powder control: characteristics and application of pneumatic cement butterfly valve

    In the cement manufacturing and processing industry, precise control of the flow of powdered materials is key to ensuring production efficiency and product quality. Pneumatic cement butterfly valves have become one of the widely used equipment in the cement industry due to their excellent sealing performance, wear resistance, and ease of operation. This type of butterfly valve uses compressed air as a power source and drives the opening and closing of the valve plate through a pneumatic actuator, thereby achieving rapid cutting and adjustment of powdery materials such as cement.

  • Why Is a Gate Valve Not Suitable for Throttling Flow

    At LYV®, we engineer our valves with a clear understanding of their intended application. Our isolation Gate Valves are built to perform one job perfectly: providing a bubble-tight seal in the closed position and minimal flow resistance in the open position.
