Fluorine Lined Pneumatic Pipeline Butterfly Valve

  1.Structure and materials, valve body: select and use nodular cast iron, carbon steel or stainless steel materials, modeling through precision cast technology, tight quality, solid structure, high anti pressure strength, able to adapt different installation environment and working situation pressure. Adopt flange connection, connect size strictly follow the national and USA standards and other standards system, convenient to install and disassemble with various pipeline. The butterfly plate: make the metal materials as prime, surface evenly lining PTFE, PEP and other fluorine plastics, the lining thickness reasonably designed according to the valve specification and working situation requirements, generally it is at 3-8mm. The fluorine plastic has excellent chemical stability, anti corrosion and low rub coefficient, not only able to validly resist various types strong corrode medium invade, still able to make better sealing between butterfly plate and valve base, reduce operating tor…
