  • What Makes Gate Valves Essential for Industrial Applications?

    Gate valves are one of the most widely used valves in industrial piping systems. They play a critical role in regulating the flow of liquids and gases, ensuring that industrial processes operate efficiently and safely. Companies like Zhejiang Liangyi Valve Co., Ltd. specialize in producing high-quality gate valves that meet rigorous standards for performance, durability, and reliability.

  • 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 Can a Check Valve Truly Prevent Water Hammer in Your Piping System

    The real question we often get asked is, what is the root cause and how can it be stopped. Having reviewed countless technical documents and case studies, I can tell you that a properly selected and installed check valve is not just a part of the solution—it's often the most critical one.

  • 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.

  • 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 is the difference in the use of butterfly valves and gate valves?

    The main differences between butterfly valves and gate valves in use are their working principles, structures, flow control capabilities, applicable scenarios, and advantages and disadvantages. ‌
