The working principle of ball valve is introduced
The working principle of the ball valve is to achieve the purpose of opening or closing the valve by rotating the opening and closing parts (spheres) around the axis of the valve stem. Specifically, when the handle or drive is rotated, the valve stem will rotate the ball with it. When the intern...Read more -
What is a ball valve?
Ball valve is a common type of valve, which is widely used in industrial pipeline control. The following is a detailed description of the ball valve: Definition and how it works Definition: Ball valve is a ball with a circular channel as the opening and closing parts, the ball rota...Read more -
Differences and similarities between Chinese valve factories and European valve factories
1. Different design concepts China valve manufacturers emphasizes price advantage and reliability, most Chinese valve manufacturers are mainly limited to low-cost and low-tech fields. European valve manufacturers emphasize innovative design, advanced technology, excellent quality and other charac...Read more -
What is Shutdown Valve (SDV)
What is Shutdown Valve A shutdown valve (also referred to as SDV or Emergency Shutdown Valve, ESV, ESD, or ESDV) is an actuated valve designed to stop the flow of a hazardous fluid upon the detection of a dangerous event. his provides protection against possible harm to people, equipment or the ...Read more -
The global ball valve market is expected to reach
Ball valve is a common valve, widely used in a variety of fluid fields. It has the characteristics of good sealing performance, fast opening and closing speed, long service life, strong adaptability to the medium and so on, and has become one of the indispensable important components in modern in...Read more -
The difference between a plug valve and a ball valve
Plug Valve vs. Ball Valve: Applications & Use Cases Due to their simplicity and relative durability, ball valves and plug valves are both used extensively in a wide range of piping systems. With a full-port design that enables unrestricted media flow, plug valves are...Read more -
When cleaning all-welded ball valves, do these things well
Installation of fully welded ball valves (1) Hoisting. The valve should be hoisted in the correct way. To protect the valve stem, do not tie the hoisting chain to the handwheel, gearbox or actuator. Do not remove the protective caps at both ends of the valve sleeve before welding. (2) Welding. Th...Read more -
How to ensure the performance of the knife gate valve?
Knife gate valves are widely used and can be used in paper mills, sewage plants, tailgate processing plants, etc. The performance of knife gate valves may become worse and worse in the process of continuous use, so under actual working conditions, how to ensure What about the performance of the k...Read more -
The principle and main classification of plug valve
The plug valve is a rotary valve in the shape of a closing member or a plunger. By rotating 90 degrees, the channel port on the valve plug is the same as or separated from the channel port on the valve body, so as to realize the opening or closing of a valve. The shape of the plug of the plug val...Read more -
Principle and failure analysis of DBB plug valve
1. The working principle of DBB plug valve DBB plug valve is a double block and bleed valve: a single-piece valve with two seat sealing surfaces, when it is in the closed position, it can block the medium pressure from the upstream and downstream ends of the valve at the same time, and is clamped...Read more -
Comparison of wear-resistant valves and ordinary valves
There are many common problems with valves, especially the common ones are running, running, and leaking, which are often seen in factories. The valve sleeves of general valves are mostly made of synthetic rubber, which has poor comprehensive performance, resulting in ex...Read more -
Traditional ball valve and segmented V-shaped ball valve
Segmented V-port ball valves can be used to efficiently control midstream production operations. Conventional ball valves are specially designed for on/off operation only and not as a throttle or control valve mechanism. When manufacturers try to use conventional ball valves as control valves thr...Read more
