Product Description

Product description
Triple eccentric butterfly valve, triple eccentric hard-sealed butterfly valve, adopts triple eccentric structure design, the valve plate has no friction with the valve seat in the full range of opening and closing, which eliminates the valve seat wear caused by the opening and closing of the rotary control valve. The leakage caused. The valve seat adopts a multi-level structure, and the sealing surface is formed by the combination of metal and non-metal materials. It performs well under high temperature and low temperature conditions. This series of butterfly valves have a long service life and excellent sealing performance, which is suitable for the adjustment and cut-off of almost all gases and liquids in industrial process control.
