Ball Valve Overview The ball valve evolved from the plug valve. Its closing element is a spherical ball that rotates 90° around the valve stem axis to open or close the valve. Unlike plug valves, the ball valve’s plug is spherical with a circular bore or passage running through its axis. When the ball rotates 90°, the inlet and outlet are completely blocked by the solid ball s...

In industrial fluid control systems, ball valves are one of the most widely used valve types due to their compact design, rapid opening and closing, and excellent sealing performance. However, during the selection process, many engineers and users often have a common question: Do ball valves affect water flow? This article will explore the actual impact of ball valves on water flow from the perspe...

In industrial pipeline systems, ball valves and other regular valves each have distinct characteristics, making the selection process crucial for different operating conditions. 1. Structure and Operating Principle Ball Valves use a spherical closure element to control fluid flow by rotating 90°. With a straight-through flow path, they offer minimal flow resistance and quick operation. ...

A gate valve is considered better than a ball valve in certain applications due to its design and functional advantages in specific conditions. Here are some key reasons why a gate valve might be preferred over a ball valve: 1. Flow Control Gate Valve: Designed for full, unobstructed flow when fully open, allowing fluids to pass with minimal resistance. It is ideal for on-off control but not as su...

As a valve widely used in fluid control systems, the ball valve is typically regarded as an efficient shut-off valve. Its unique structural design allows it to fully open or close the pipeline with just a 90-degree rotation, achieving rapid shut-off or opening of the media flow. Therefore, ball valves are widely used as shut-off valves in various industrial applications, especially in situations r...

A ball valve does not always need to be fully open, but whether it should be fully open or not depends on the application and the design of the valve. 1. Designed for On/Off Control Ball valves are typically designed for full on/off control, meaning they function best when they are either fully open or fully closed. This is because they allow for minimal resistance to flow when fully open and prov...

Ball valves are widely used in various industrial sectors due to their simple structure, excellent sealing performance, and ease of operation. However, during long-term use, ball valves may develop leaks. Leaks not only lead to the waste of media but can also disrupt the normal operation of the system and even pose safety risks. Common Reasons 1. Aging or Damage of Sealing Materials The sealing pe...

In industrial applications, ball valves are widely used in fluid control systems due to their simple operation and reliable performance. Among them, Orbit Ball Valves and conventional ball valves are two common types. Although they may appear similar, there are significant differences in their structural design, operating principles, application scenarios, and performance. 1. Structural Design Orb...
