Product details

Vacuum butterfly valve is a valve used in vacuum systems to regulate air flow, cut off and connect pipelines, mainly used to control air and non corrosive gases. It works based on the principle of rotational adjustment, and achieves valve opening, closing, and flow regulation through the rotation of the valve disc. The characteristics of vacuum butterfly valves include simple structure, light weight, easy installation, small space occupation, and good sealing performance in high vacuum environments. In addition, it also has good flow regulation performance and can achieve precise flow control according to actual needs.

Structure and working principle

The core components of a vacuum butterfly valve include a stainless steel structure valve body, valve disc, and valve stem. The valve disc is usually connected to a pneumatic or electric actuator through a valve stem, and can rotate inside the valve body to control the flow of the medium. The material of the valve body is usually selected to be corrosion-resistant and high-temperature resistant, such as stainless steel or other special alloys. The angle of rotation of the valve disc determines the degree of valve opening, thereby controlling the flow rate of the fluid.

Application

Vacuum butterfly valves are widely used in applications that require high vacuum environments and precise fluid control, such as the chemical industry, pharmaceutical manufacturing, food processing, scientific research, and other fields. In these fields, vacuum butterfly valves are used to control the flow of gases or liquids, ensuring stable operation of equipment in high vacuum environments.

The vacuum butterfly valve is designed specifically for vacuum environments, with a unique structure and sealing performance, suitable for systems that require maintaining a vacuum state. In contrast, other valve types such as ball valves, globe valve,gate valves, etc., although also available in vacuum versions, are designed with a greater emphasis on positive pressure applications and are suitable for a wider range of industrial and commercial pipeline systems. When selecting valves, the most suitable valve type should be determined based on specific application scenarios, working conditions, and medium characteristics.
