2、 Detailed information

Product Overview

The triple offset butterfly valve can be suitable for various harsh working conditions. Its eccentric design allows the sealing pair to detach immediately when the valve is opened, reducing friction between sealing surfaces, greatly improving the service life of the valve. At the same time, it has essential fire resistance characteristics and is widely used in industrial pipelines such as metallurgy, power, petrochemical, air, water supply and drainage, and municipal construction, for regulating flow and cutting off fluid.

Design and inspection can comply with standards such as API 609, GB/T 12238, JB/T8527, etc.
