Key Advantages and Common Types of Plug Valves

In a significant stride forward in valve engineering, the plug valves have emerged as a groundbreaking solution, effortlessly opening or closing with just a 90-degree rotation, aligning or separating the flow passages on the plug and valve body. The plug in a plug valve can take the shape of a cylinder or a cone. In cylindrical plugs, the flow passage is typically rectangular, while in conical plugs, it adopts a trapezoidal form. These evolving shapes contribute to the lightweight structure of plug...

Differences Between Plug Valves and Ball Valves

Plug Valve: The plug valve is an older type of valve that relies on the rotation of a plug around the valve body's central axis to achieve opening and closing. It is primarily used for cutting off, distributing, and changing the direction of the medium flow. Ball Valve: Evolving from plug valves, ball valves operate using a spherical ball as the closure component. These valves are versatile and commonly employed for applications requiring shut-off, distribution, and flow direction alteration....

Comprehensive Guide to Selecting Between Electric and Pneumatic Ball Valves

Ball valves have the capability to integrate with either a pneumatic actuator, resulting in pneumatic ball valves, or an electric actuator, giving rise to electric ball valves, facilitating automation and remote control. The choice between automating with a pneumatic actuator or an electric one depends on the specific application, with each option offering distinct advantages. In this article, we will conduct a comparative analysis of these two alternatives. 1. Understanding Electric and...

Hard Seal Butterfly Valves: Characteristics, Advantages and Maintenance Guidelines

Butterfly valves, based on their sealing states, are categorized into soft seal and hard seal variants. The commonly used soft seal includes fluorine-lined butterfly valves, while the hard seal category encompasses metal hard-seal disc valves. Hard seal butterfly valves refer to valves where both sides of the sealing pair consist of metal or other relatively hard materials. While hard-seal butterfly valves may exhibit inferior sealing performance, they boast high-temperature resistance, wear resistance,...

Contrasts Between O-Type and V-Type Ball Valves

Ball valves come in various structures, but their basic components, such as the circular ball core, valve seat, ball, sealing ring, valve stem, and other driving devices, are similar. These valves operate by rotating the stem 90 degrees to open or close the valve, playing a crucial role in pipeline applications for shut-off, distribution, flow regulation, and altering the direction of the medium. The choice of valve seat sealing depends on the specific working conditions. O-Type Ball Valve Structure:...

Comparing Features of Floating Ball Valves and Fixed Ball Valves

Floating Ball Valve: The ball in a floating ball valve is movable, and under the pressure of the medium, it can generate a certain displacement and press tightly against the sealing surface at the outlet to ensure sealing. The floating ball valve has a small volume, light weight, simple structure, and excellent sealing performance. However, the ball transfers all the loads from the working medium to the outlet sealing ring, so it is essential to consider whether the sealing ring material can withstand...
