  • 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.

  • Why is the Triple Offset Butterfly Valve Designed with Three Eccentrics?

    The triple offset butterfly valve is an industrial control valve that achieves sealing through three geometric offsets. The core feature is the non-concentric layout of the valve stem, valve plate and sealing surface.

  • What are the Advantages of Double Offset Resilient Seated Butterfly Valve Compared with Ordinary Valves?

    Double offset resilient seated butterfly valve is an industrial valve that combines two geometric offsets with elastic sealing components.

  • 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.

  • Sharing of maintenance methods for pneumatic triple eccentric butterfly valve

    Pneumatic triple eccentric butterfly valve is a valve based on pneumatic actuator for switch control. It has a simple structure, easy operation, and good sealing performance, and is widely used in various industrial fields. In order to ensure its normal operation and extend its service life, we need to carry out regular maintenance work.

  • 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.
