  • 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.

  • Can A Gate Valve Be Used For Throttling Flow In Pipeline Systems

    When clients ask us whether a gate valve is suitable for throttling flow, our answer is always straightforward: it’s not recommended. Having designed and supplied valves for industrial systems over the past two decades, we’ve seen firsthand the consequences of using valves in ways they weren’t engineered for. So why is this such a common question? And what should you use instead?

  • What Are the Main Advantages and Disadvantages of Globe Valves

    As someone who has worked with countless clients on their piping systems, I often find that the Globe Valve is both praised and questioned. At LYV, we believe in clear, honest information to help you make the best decision. This valve, named for its spherical body shape, is a cornerstone for precise throttling and shut-off in many industrial and commercial applications. Let’s dive into its core strengths and limitations to see if it’s the right fit for your project.

  • 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.

  • Where the Ball Valve is used.

    Because the ball valve usually uses rubber, nylon and polytetrafluoroethylene as the seat sealing ring material, its use temperature is limited by the seat sealing ring material.
