What seat, valve plate, valve shaft, valve body of gypsum slurry flange butterfly valve?
Valve plate materialThe choice is critical, due toNi-Cr-MoThere are many kinds of alloy materials, which are roughly divided into Mongolia and MongoliaHastelloy and HastelloyIn flue gas desulfurization slurry valve butterfly valve is mostly used in Europe and the United States Hastelloy butterfly plate material
In terms of butterfly valve, the main part of contact with the media is the valve plate and sealing ring, in view of the characteristics of the slurry,The valve plate is mainly usedNi-Cr-MoAlloy material, the sealing ring adopts wear-resisting anticorrosive sealing ring.
In wet flue gas desulfurization, the butterfly valve is usually used under the condition of large diameter, and the diaphragm valve is used for small diameter.For butterfly valve, due to the jet of slurry, the butterfly plate can not be used in the form of anti-corrosion coating.
