Center line soft seal butterfly valve: A reliable fluid control partner for the chemical industry


In chemical production processes, it is often necessary to transport various corrosive media, such as strong acids like sulfuric acid and hydrochloric acid, and strong alkaline solutions like sodium hydroxide. The sealing surface of the centric soft-sealed butterfly valve uses special soft sealing material.

In the chemical industry, the precision and safety of fluid control are paramount. 
Chemical production processes often require the transfer of various corrosive media, such as strong acids like sulfuric acid and hydrochloric acid, and strong alkaline solutions like sodium hydroxide. The sealing surface of the center-line soft-sealed butterfly valve uses special soft sealing materials, which have excellent corrosion resistance and can effectively resist the corrosion of these strong acids and alkalis, ensuring that the valve will not leak during long-term use. For example, on the production line of a large chemical enterprise, center-line soft-sealed butterfly valves are widely used in pipelines transporting various corrosive media, and after years of operation, they still maintain good sealing performance, providing strong support for the safe production of the enterprise. 
In addition, the center-line soft-sealed butterfly valve is also characterized by its compact structure and flexible opening and closing. In chemical production, it is often necessary to quickly cut off or adjust the fluid to meet different production process requirements. The center-line soft-sealed butterfly valve can be fully opened or closed in a short time, is easy to operate, has a fast response speed, and effectively improves production efficiency. At the same time, its flow resistance coefficient is small, and it will not cause large resistance to fluid transport, which helps to reduce energy consumption and save production costs.
