Pneumatic triple eccentric butterfly valve

ADVANTAGES

Pneumatic triple eccentric butterfly valve, using triple eccentric multi-level metal hard seal structure, is widely used in metallurgy, electric power, petrochemical industry, as well as water supply and drainage and municipal construction and other industrial pipelines. Pneumatic tripple eccentric butterfly valve can adjust the flow and cut off the fluid, it has the double advantages of metal hard seal and elastic seal, no matter in the case of low temperature and high temperature, have excellent sealing performance, corrosion resistance, long service life and other characteristics.
