The lined butterfly valve adopts the lining process for all the places in the valve body that the medium can reach. The lining material uses FEP (F46) and PCTFE (F3) and other fluoroplastics, which can be applied to various concentrations of sulfuric acid, hydrochloric acid, hydrofluoric acid, and Water and various organic acids, strong acids.
4. Advantages of Lined Butterfly valves.
Because PTFE has strong corrosion resistance, stable performance, not easy to aging, low friction coefficient, easy to form, stable size, and can also be filled and added with appropriate materials to improve its comprehensive performance, the metal hard sealing butterfly valve with better strength and lower friction coefficient can be obtained. The lined butterfly valve has a wider range of temperature and pressure, better sealing performance and service life Longer.
