What Are The Advantages And Features Of Lined Ball Valve?
We often use Lined Ball Valve in our daily lives and work, but are you familiar with "pneumatic eccentric semi-ball valves"? This article compiles some information about pneumatic eccentric semi-ball valves, hoping it will be of great reference value to users.
Pneumatic eccentric semi-ball valves utilize an eccentric valve body, eccentric ball, and valve seat. The valve stem automatically centers along a common trajectory during rotation, tightening as it closes, achieving a perfect seal. The ball and seat are completely separated, eliminating wear on the sealing ring and overcoming the persistent wear between the seat and the ball sealing surface in traditional ball valves. Non-metallic elastic material is embedded in the metal seat, effectively protecting the metal seat surface. This product is particularly suitable for use in the steel and aluminum industries, as well as for media such as fiber, fine solid particles, pulp, fly ash, and petroleum gas.
Pneumatic eccentric semi-ball valves and eccentric semi-ball valves are similar valves, differing in their power source. Eccentric semi-ball valves use a ball that rotates around the centerline of the valve body to open and close. Ball valves are primarily used in pipelines to cut off, distribute, and redirect the flow of media. Two-piece and three-piece ball valves are a new type of valve that has become widely adopted in recent years, and pneumatic half-ball valves are also increasingly being adopted across various industries.
They offer low fluid resistance, with a resistance coefficient equivalent to that of a pipe section of the same length. They are simple in structure, compact, and lightweight. They are tight and reliable. Plastics are currently widely used for the sealing surfaces of ball valves, providing excellent sealing properties and making them widely used in vacuum systems. They are easy to operate and open and close quickly, requiring only a 90° rotation from fully open to fully closed, facilitating remote control. Maintenance is also convenient, with a simple structure and removable sealing rings, making them easy to disassemble and replace. When fully open or closed, the sealing surfaces between the ball and seat are isolated from the media, preventing erosion of the valve sealing surfaces when the media passes through. They are suitable for a wide range of applications, ranging from small diameters of a few millimeters to several meters, and for applications from high vacuum to high pressure.
