Desulfurization dedicated butterfly valve is my company under current domestic FGD system design products. To meet the limestone and gypsum slurry grout corrosion, and the valve stem plate using a special corrosion-resistant alloys, high-valve seat wear rubber meet the large number of suspended particles in the liquid on the valve seat erosion. Therefore products with high wear-resistance and anti-corrosion of high. The product is designed to address user requirements, targeted and high reliability. Suitable Mediums: sulfur dioxide, lime slurrypaste, process water and other corrosive media.
