The valve body and trim of the L-21241C series are fully lined with fluorine, which effectively protects the mental material from corrosive fluids. The inner cavity of the metal valve body is processed in a toothed manner, which enables the lining material to connect with the metal, prolonging the service life and enhancing the performance of the lining material. The stem is sealed by a combination of RTFE bellows and “V” type PTFE packing to eliminate external leakage. The unbalanced fully fluorine-lined global valve is applicable for the use of highly corrosive media under low pressure and normal temperature conditions.
