Product Advantage
·PTFE lined butterfly valve is suitable for transporting various toxic and highly corrosive chemical gases and liquids. It has good anti-corrosion performance and is suitable for sulfuric acid, sodium hydroxide, potassium hydroxide, neutral salt solution and ammonia liquid, cement, and clay , cinder ash, granular fertilizers and highly abrasive solid fluids with various concentrations and thick liquids, etc.
·Passed multiple sealing safety tests. The valve body is equipped with an oil sealing back-up ring, and there is no visible gap between the sealing pairs, achieving zero leakage. The expansion gap between the butterfly plate and the valve body is large, which can effectively prevent jamming caused by thermal expansion and contraction;
·The valve body adopts a split double valve body structure design, which can be installed in any position, is easy to maintain, and meets the requirements of various working conditions;
·PTFE lined wafer butterfly valve has short structure size, light weight and easy installation.
