Pneumatic high-performance butterfly valve

Overview:

The pneumatic high-performance butterfly valve adopts a unique eccentric structure. The valve plate uses a unique spherical arc linear surface body. The valve plate and the valve seat achieve linear surface contact in the middle. The sealing structure achieves a true dynamic seal through pipeline pressure. It is superior to ordinary soft-sealed butterfly valves in high-temperature (hard-sealed), high-pressure and high-frequency applications, avoiding the "tearing" phenomenon between the valve plate and the valve seat. It is widely used in industries such as metallurgy, chemical engineering, power, papermaking, food and medicine.
