        LPB14 -High-performance Butterfly Valve
             
        The butterfly valve adopts two-section shafts ,top shaft and bottom shaft.There is no raised axial girder on the central disc,which reduces  block area in the middle of channel.The shaft is thicker than the normal shaft,with stronger pressure resistance and more firm connection with disc.The valve seat uses seat back with vulcanized rubber technology which avoid being damaged when there flows too dry gas and powder. And it is not applicable to high-temperature and granular media.
         
        ■ Stainless steel valve body and FTFE valve seat can be selected.
        ■ The up and down holes of disc adopts spherical friction surface design. Torque is smaller and sealing is better.
        ■The life of valve seat is longer in the case of too dry gas and powder.
        ■The Flange hole applies to many standards.
