The Butterfly Valve has a simple structure and is a pipeline control valve that is more convenient to use than other valves. It is applied in various industrial pipeline systems. Its core component is a disc-shaped valve plate, which controls the flow of medium in the pipeline by rotating it. When the valve plate rotates parallel to the pipeline, the valve is fully opened; When rotated 90 degrees perpendicular to the pipeline, the valve is completely closed. This unique working principle gives this product the characteristic of rapid opening and closing.
What are the different types of Butterfly Valves?
According to different classification standards, it can be divided into multiple types: clamp type, flange type, and welded type according to the connection method; According to the sealing material, it can be divided into soft seals such as rubber and polytetrafluoroethylene, and metal hard seals; According to structural design, it can be divided into medium eccentricity, single eccentricity, double eccentricity, and triple eccentricity; The driving methods include manual (handle, worm gear), electric, pneumatic, and hydraulic, etc. Zhejiang Zhongguan Valve can produce products of the above categories, including varieties of different structures and materials. Our product can be used for both ordinary water pipes and industrial pipelines with high temperature and pressure, meeting different needs and is the preferred choice for our customers.
Why is synthetic rubber valve seat the preferred sealing material?
Synthetic rubber is widely used in valve seats. Due to the characteristics of corrosion resistance, dimensional stability, and low cost, synthetic rubber can be selected with different properties according to different usage requirements to meet various working conditions. In the new era of constantly evolving technology, the performance of products is also gradually improving. For example, the three eccentric Butterfly Valve adopts a special structural design, greatly improving the sealing performance and service life; Some sealing rings made of special materials can adapt to more demanding working environments. In terms of intelligence, equipped with electric or pneumatic actuators, remote control and automated operation can be achieved.
Butterfly Valves have a wide range of applications. If used to control flow, different types and valve body sizes need to be selected, as they are already suitable for valves with larger diameters during design. It is widely used not only in general industries such as petroleum, gas, chemical, and water treatment, but also in the cooling water system of thermal power plants.
