  • The main components of the Ball Valve.

    Ball valve was born in the 1950s, with the rapid development of science and technology, the continuous improvement of production process and product structure, in a short time...

  • 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 is the structure and characteristics of a butterfly valve?

    Butterfly valves have the characteristics of simple structure, small volume, light weight, low material consumption, small installation size, fast switching, 90 ° reciprocating rotation, and small driving torque. They are used to cut off, connect, and regulate the medium in pipelines, and have good fluid control characteristics and closing sealing performance.

  • Why are pneumatic valves more commonly used than electric valves for important valves?

    neumatic valves have inherent safety features. In complex working environments, there are many electrical devices and potential sources of electrical interference. Electric valves rely on electric power for operation, and when electrical faults occur—such as short circuits, leakage, overloads, or electromagnetic interference—there is a high risk of malfunction in their control systems. For example, near areas with strong electromagnetic radiation, electric valves might receive incorrect signals, causing them to open or close unexpectedly, which can pose significant safety hazards to the entire system's operation.

  • Selection of Valves and Their Appropriate Locations

  • 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.
