D673HPneumatic butterfly valveOverview： 

D673HPneumatic butterfly valve utilizes preciseJForm elastic seal rings and triple eccentric multi-layer metal hard seal structures are widely used in medium temperature≤425℃In industrial pipelines for metallurgy, electricity, petrochemicals, water supply and drainage, and municipal construction, this valve is used for regulating flow and cutting off fluids. The valve features a triple eccentric structure, with both the valve seat and the disc plate sealing surface made from different hardnesses and stainless steel, offering excellent corrosion resistance and a long service life.。

D673HPneumatic butterfly valveFeatures：

1、D673HThe pneumatic butterfly valve features a three eccentric sealing structure, with the valve seat and butterfly plate experiencing minimal wear, offering a sealing function that becomes tighter with use.
2、D673HThe pneumatic butterfly valve seals are made of stainless steel, offering the dual advantages of metallic hard sealing and elastic sealing. They maintain excellent sealing performance in both low and high temperatures, and are corrosion-resistant.,Long service life and other features.
3、D673HThe airtight butterfly valve disc seat is sealed with a surfacing weld of cobalt-based hard alloy, ensuring wear resistance and a long service life.
4、D673HHigh specification pneumatic butterfly valves feature a latticed disc structure, offering high strength, large flow area, and low flow resistance.
5、D673HThe pneumatic butterfly valve features bidirectional sealing capabilities, allowing for installation without restrictions on the medium's flow direction or spatial position, and can be mounted in any direction.
6、D673HPneumatic butterfly valve actuator can be multi-position (rotary)90°Or180°Easier installation for user convenience.
